2. ULSTER TRAVEL ANNOUNCES ASTRONOMY RELATED TRIPS PLANNED FOR THE NEXT FEW YEARS

Following on the great success of its Solar Eclipse trip to China in 2009, Ulster Travel is planning a series of exciting astronomy themed adventures over the next few years.

The trips have been planned with the assistance of Terence Murtagh, former Director of Armagh Planetarium, former President of the International Planetarium Society and well-known director and producer of astronomy based television and giant screen programmes around the world.

On 21 April Ulster Travel will be presenting on the huge dome of the Armagh Planetarium an overview of these planned events and a special premiere of  "The Secret Lives of Stars" production.

Please register your interest for this event asap, by contacting Ann Relph at info@ulstertravel.com

Using the spectacular dome of the planetarium we will present an overview of these planned trips together with amazing images in the all dome format of what you can expect to see. Here's a short summary of some of the fascinating experiences we plan to cover.

NORTHERN LIGHTS – TROMSO NORWAY:

As solar activity continues to build up so displays of the Aurora are becoming more frequent and energetic. One of the easiest to reach viewing places with a good record of Auroral sightings is the Norwegian coastal City of Tromso. Set amidst majestic mountains and the sea Tromso, is often under the Auroral oval and has already experienced so magnificent displays this year.

The Ulster Travel group will stay in a hotel away from the bright city centre with ample opportunities to move go out to darker regions. A special course in night sky photography will be given. A Canon 5D MK II camera will be available to enable everyone to have the opportunity of capturing their own image of the heavens at their most spectacular. Several trips will be offered throughout the Autumn and Spring periods starting in 2011.

ATACAMA SKIES

We are looking at the possibility of offering special visits to Northern Chile so visitors can experience the brilliance and beauty of the southern Milky Way. The trips would be in either June or July and be timed to take advantage of the best opportunities to see the Galactic Centre at its most glorious. Famed for its magnificent viewing conditions the Atacama gives everyone the opportunity to see, explore and photograph the Milky Way Galaxy in all its splendour.

"STARS OF THE PHARAOHS" August 2011

A wonderful opportunity to explore with family and friends the amazing world of the ancient Egyptians with a special emphasis on the astronomical nature of some of their greatest monuments. Not many people are aware of the beautiful astronomical alignments and decoration of many Egyptian temples and tombs.

The ancient Egyptians used their observations of the stars to regulate their calendars, establish buildings and were probably the first to measure exact duration of the year. The tour will begin with the Great Pyramids at Giza and a visit the famous Egyptian Museum in Cairo with its treasures from the Tomb of Tutankamun.

Moving on to Luxor we will use this amazing city as a base to visit some of the most spectacular temples and tombs. In the valley of the Kings we hope to visit a tomb with a most amazing astronomical ceiling, and also that of Tutankamun, which has its own special story related to the heavens.

On a different scale there is the fabulous ruined Ramasseum with fascinating inscriptions on the ceiling relating to how the lunar and sidereal calendars were synchronised. Then there are the temples of Esna and Dendarah. Both of these have fascinating ceiling panels relating to the planets, the phases of the Moon as well as beautiful freezes showing the major constellations.

Dendarah is also famed for its intriguing Star map known as the Dendarah Zodiac. An optional 4-day cruise down lake Nasser to the great Temple of Abu Symbel is also available at a special price.

Abu Symbel the most beautiful of Rameses II's temples was cut from the rock. It was reconstructed above the waters of lake Nasser but is still sited so that twice a year the rays of the rising sun illuminate the faces of the gods far inside. These dates mark the anniversaries of the birthday of Rameses II and his accession to the throne of Egypt.

A fascinating trip for astronomy and non-astronomy buffs alike. It will be conducted at a leisurely pace and use some of most highly rated hotels in Egypt.

ECLIPSE YEAR 2012

2012 is a great year for eclipses watchers. An annual eclipse of the Sun in early summer, a rare Transit of Venus and a beautiful total eclipse of the Sun at the beginning of Spring in the Southern Hemisphere.

Ulster Travel is planning to run two eclipse tours that year.

ANNULAR ECLIPSE USA

May 2012 sees a beautiful annular eclipse of the Sun. It begins in the Far East , crosses the Pacific, and ends over some of the most spectacular scenery in the Western USA.

Ulster travel is planning to offer a viewing trip that would include visits to Meteor Crater in Arizona, Flagstaff Observatory and the Grand Canyon. The eclipse-viewing site would be in one of the most scenic National Parks in the USA.

Option excursions could include a visit to additional national Parks in Southern Utah and visits to the Kitt peak Observatories outside Tucson in Arizona.

TOTAL ECLIPSE AUSTRALIA 2012

On Nov 14th (local time) a total eclipse of the Sun will take place and be visible in the morning sky of North East Australia.

The area around Cairns, particularly the coastal strip looking East over the Ocean is usually blessed with clear skies at this time of the year.

It's likely that this will be an extremely popular eclipse and that accommodation will be in short supply as one of the smaller towns in the path of totality is planning an eclipse marathon with many thousands of runners planning to attend.

Ulster Travel has already had the various sites and hotels inspected and a full report on the possible viewing sites, weather conditions and all other factors will be made during the presentation in the Planetarium.

We will be offering two trips each of which could have other options added.

One trip would be a straightforward visit to Cairns, principally for the eclipse. Optional extras would include local car hire, rainforest and barrier reef adventures.

The other would be more astronomically aligned. Visits would be made to some of Australia's best-known sites of astronomical interest. These would include former Anglo-Australian telescope, the historic Parkes radio telescope, and the opportunity to use telescopes to explore the southern stars from a good dark sky site. No visit to Australia would be complete without a visit to one of the country's national parks where local wildlife, Kangaroos, Emus' ad Koalas are to be found.

Optional extras include visits to the Henbury Meteorite craters near Alice Springs and a possible flight over the vast ancient impact site known as Gosses Bluff.

More details on these planned adventures will be made available soon. You are welcome to register your interest in any of these exciting trips by contacting Ann Relph at Ulster Travel: info@ulstertravel.com.

3. The ISS has just started a series of evening passes over Ireland. If you check the details for your location on www.heavens-above.com, you may find some passes that coincide, or nearly so, with passes of Nanosail-D - see below. A nice touch for the Nanosail photo competition would be to capture both satellites in the same shot, but I think that the chances of getting both at the same time, in the same field of view, would be quite low. Still, check it out - you never know.

4. NANOSAIL-D: NASA's first Earth-orbiting solar sail, NanoSail-D, is circling our planet and attracting the attention of sky watchers. Occasionally, sunlight glinting from the sail's reflective fabric produces a flash of light in the night sky. These "solar sail flares" are expected to grow brighter as NanoSail-D descends in the weeks ahead.  A series of morning passes continues, some of which are quite favourable. Details of passes for your own location are on www.heavens-above.com.
   NANOSAIL-D AMATEUR ASTRONOMY IMAGE CONTEST
NASA has formed a partnership with Spaceweather.com to engage the amateur astronomy community to submit the best images of the orbiting NanoSail-D solar sail. NanoSail-D unfurled the first ever 100-square-foot solar sail in low-Earth orbit on Jan. 20.
   To encourage observations of NanoSail-D, Spaceweather.com is offering prizes for the best images of this historic, pioneering spacecraft in the amounts of $500 (grand prize), $300 (first prize) and $100 (second prize).
   The contest is open to all types of images, including, but not limited to, telescopic captures of the sail to simple widefield camera shots of solar sail flares. If NanoSail-D is in the field of view, the image is eligible for judging.
   The solar sail is about the size of a large tent. It will be observable for approximately 70 to 120 days before it enters the atmosphere and disintegrates. The contest continues until NanoSail-D re-enters Earth's atmosphere.
   NanoSail-D will be a target of interest to both novice and veteran sky watchers. Experienced astrophotographers will want to take the first-ever telescopic pictures of a solar sail unfurled in space.  Backyard stargazers, meanwhile, will marvel at the solar sail flares
-- brief but intense flashes of light caused by sunlight glinting harmlessly from the surface of the sail.
   NanoSail-D could be five to 10 times as bright as the planet Venus, especially later in the mission when the sail descends to lower orbits.
 See http://science.nasa.gov/science-news/science-at-nasa/2011/01feb_solarsailflares/ 

5. SECRET SATELLITES: Check out the "Secret Satellites Exhibition" in Belfast, at which Professor Mark Bailey, Director of Armagh Observatory, will be featuring. See details at http://www.belfastexposed.org/exhibitions/index.php

 
6. Lyrid Meteors: The annual Lyrids meteor shower will peak on Friday 22 April. It's not normally the year's most spectacular shower, with a ZHR of about 10, but there have been some unusually good displays, such as in 1982, so it's worth having a look anyway. The radiant is near Vega. The view will be somewhat spoiled later in the night when the waning gibbous moon rises, so watch the sky as soon as it gets totally dark; then later when the moon rises, try to hide it behind a building or similar, so it does not shine directly into your eyes.

6. NEW RUSSIAN SPACE PLANS: Russia will test a next-generation spacecraft, build a new launch site and even consider a manned mission to Mars, the nation's space chief has promised.

   But Anatoly Perminov admitted Russian spacecraft still depend on imported electronics, speaking a day after the nation celebrated the 50th anniversary of the first human spaceflight by Yuri Gagarin on April 12, 1961.
   "We have to acknowledge that imported components account for 65-70% of electronics in the spacecraft launched last year and those set to be launched this year," he said.
    Russian President Dmitry Medvedev this week vowed that space will remain a key government priority, but sceptics said the nation has done virtually nothing to develop a successor to the 43-year-old Soyuz spaceship.
   Russia has used the Soyuz and Progress spacecraft, whose designs date back to the 1960s, to send an increasing number of crew and cargo to the International Space Station. They will become the sole link to the space outpost after the US space shuttle Atlantis closes out the US programme this summer.
   Some cosmonauts warned, however, that while Russia stands to reap short-term benefits from its monopoly in ferrying crews and supplies to the space station, it could quickly fall behind America after the US builds a new-generation Orion spaceship.
   Russian officials have set a tentative launch of a new spacecraft to replace Soyuz for 2015, but cosmonauts and industry watchers have said its development has barely begun.
    Mr Perminov said Russia will need to make at least 15 successful unmanned launches of the new craft, named Rus, before it can carry crew into orbit.
    He also said Russia will this year start building a new launch pad in Russia's Far East, called Vostochny. Officials have said the first launches from Vostochny are expected in 2015. Russia is now using the Soviet-built Baikonur cosmodrome in Kazakhstan for all its manned space flights and a large share of its satellite launches. Russia has a lease on Baikonur until 2050.

Lecture, Supermoon, G.A.N, Earth Hour, Nanosail-D, COSMOS

Hi all,
 
(A few of you on this mailing list were accidentally omitted from previous bulletins - apologies. T.M.)
 
1. IAA LECTURE MEETING: "Widefield Astro-imaging: the French Connection".  23 March, 7.30 p.m., Bell Lecture Theatre, Physics Department, QUB. The next lecture in the Irish Astronomical Association Lecture Programme, will be by IAA member Martin Campbell: Martin is a renowned astronomical photographer, and not only won the IAA's IYA 2009 astrophotography competition, but was also the overall winner of the grand prize for best entry in any category. Martin regularly travels to exceptionally dark high altitude sites in France to obtain really spectacular images, which he will be showing at this lecture. But the stunning images he submitted for the IYA 2009 competition were all taken in Ireland, showing just what can be achieved from here.
    Even if you have no interest in astrophotography, this is sure to be a fascinating lecture.  Admission is free, including light refreshments, and all are welcome. There is free parking on the QUB site after 5.30 p.m.
  For details of all forthcoming IAA lectures and other events, see www.irishastro.org  

2. "Supermoon".  Well, the Full Moon on and around 19 March was indeed unusually big and bright, as it coincided with a very close Perigee. but as I predicted in earlier E/Ms, there were none of the alarmist internet-predicted catastrophes of earthquakes, volcanic eruptions, or major weather events. Just to emphasise the point, the terrible Japanese earthquake on 11 March occurred when the Moon was still closer to apogee than perigee, i.e. it was further away from Earth than its average distance. And even the largest of the aftershocks occurred well before the FM/Perigee.

3. Earth Hour. Earth Hour takes place between 8:30pm and 9:30pm on Saturday evening, March 26 and everyone around the globe is urged to turn off their lights and to not use power for that one hour. Prime Minister David Cameron has backed this campaign, which is aimed at saving the environment, saving energy and reducing pollution, but of course it's of particular interest and benefit to astronomers to have less artificial lighting at night. More information on this global energy-awareness initiative can be found at www.earthhour.org.

4. Globe At Night (G.A.N.): Less of Our Light for More Star Light: Join the second part of the 6th world-wide GLOBE at Night 2011 campaign: March 22 - April 4. With half of the world's population now living in cities, many urban dwellers have never experienced the wonderment of pristinely dark skies and maybe never will. This loss, caused by light pollution, is a concern on many fronts: safety, energy conservation, cost, health and effects on wildlife, as well as our ability to view the stars. Even though light pollution is a serious and growing global concern, it is one of the easiest environmental problems you can address on local levels.

Participation in the international star-hunting campaign, GLOBE at Night, helps to address the light pollution issue locally as well as globally. This year, 2 sets of campaigns are being offered. The first campaign ran from February 21 through March 6, 2011. The second campaign runs from March 22 through April 4 in the Northern Hemisphere and March 24 through April 6 in the Southern Hemisphere, and everyone all over the world is invited to record the brightness of the night sky. The campaign is easy and fun to do. First, you match the appearance of the constellation Orion in the first campaign (and Leo or Crux in the second campaign) with simple star maps of progressively fainter stars found. Then you submit your measurements, including the date, time, and location of your comparison. After all the campaign's observations are submitted, the project's organizers release a map of light-pollution levels world-wide. Over the last five annual 2-week campaigns, volunteers from more than 100 nations contributed 52,000 measurements, one third of which came from last year's campaign.

To learn the five easy steps to participate in the GLOBE at Night program, see the GLOBE at Night website. You can listen to last year's 10-minute audio podcast on light pollution and GLOBE at Night. Or download a 45-minute powerpoint and accompanying audio. GLOBE at Night is also on Facebook and Twitter.

The big news is that children and adults can submit their measurements in real time if they have a smart phone or tablet. To do this, you can use the web application. With smart phones and tablets, the location, date and time are put in automatically. And if you do not have a smart phone or tablet, there are user-friendly tools on the GLOBE at Night report page to find latitude and longitude.

For activities that have children explore what light pollution is, what its effects are on wildlife and how to prepare for participating in the GLOBE at Night campaign, see the Dark Skies Rangers activities. Monitoring our environment will allow us as citizen-scientists to identify and preserve the dark sky oases in cities and locate areas where light pollution is increasing. All it takes is a few minutes during the 2011 campaign to measure sky brightness and contribute those observations on-line. Help us exceed the 17,800 observations contributed last year. Your measurements will make a world of difference.

   NanoSail-D could be five to 10 times as bright as the planet Venus, especially later in the mission when the sail descends to lower orbits.
