NLCs, OM/Davagh events, OPIS, Solstice, Parade of Planets, Asteroid Day, ISS, Webinar, On the Moon, Teasers

Hi all,

 

1. NLCs. The season for seeing Noctilucent Clouds (NLCs) runs from now until late July. Look low in the North for about two hours on either side of local midnight (allowing for longitude and summer time, i.e. local midnight in Ireland is approximately 01.20 to 01.40 clock time). They appear as silvery/white streaks and wisps shining brighter against the twilit background sky. The further South you are, the less chance you have of seeing them, as they will appear much closer to the horizon.

2. OM Events at Davagh Dark Sky Park: There  will be some daytime moon and sun viewing sessions and a little 'AstronOMy' Club, plus other things related to the forest and so on. The page to check is: What's On | Guided tours at OM Dark Sky Park and Observatory

3. Our Place In Space | What's On The interactive scale model of the Solar System on Divis, just outside Belfast. See Scale model of solar system installed in Belfast hills (msn.com)  For details of the Belfast events, see:  Belfast | Our Place In Space.

4. Summer Solstice. The Sun reaches its most Northerly point on the ecliptic on 21 June at 09.13 (10.13 B/IST) marking the start of N. Hemisphere Summer.

 

5. Parade of the Planets, 20 to 28 June

During this period, all the naked eye planets will be visible together in the morning sky, in order of their distance from the Sun, although Mercury will be very low and you'll need binoculars to see it, except perhaps from the very far South of the island. The waning Moon will also be in the area, and on the mornings of 22 to 26 June, the Moon will also be in its correct order from the Sun, i.e. Mercury, Venus, Moon, Mars, Jupiter and Saturn.

Aesthetically, the nicest view will be on the 24th, with the waning crescent Moon about halfway between Venus and Mars.

To find Mercury, look about 10º below left of brilliant Venus, at an angle of about 8p.m. on a clock face. From the N of the island it won't rise until civil twilight has started, and it will be only mag -0.1 on the 24th, -0.2 on the 25th, -0.3 on the 26th, -0.4 on the 27th and -0.5 on the 28th, so binoculars or a wide-field telescope will be required.

   On the 27th, Mercury will lie below the thin crescent Moon, and that will be your last good chance to find Mercury and to be able to see the Moon in the line-up.

Uranus and Neptune will also be in the line, but not in order, and you'll need binoculars or a telescope to see them.

 

6. Asteroid Day, 30 June.

See: ASTEROID DAY LIVE - Asteroid Day

 

7. ISS: A new series of morning passes starts on 1 July, transitioning into a mixture of morning and evening passes, and then evening passes only, continuing to 28 July. Details as usual on www.heavens-above.com

 

8. Space and Astronomy Webinar returns, 4 July. The next one will be at 7.30 on Tuesday 4  July. More details and links in next bulletin

 

9. On the Moon Again is Back on 8-10 July.
You are invited to join in a global project to bring observational astronomy to the streets of communities. On the Moon Again will take place from 8-10 July. For more information, see their website; to register your activity, fill out this form.

 

10. Davagh Dark Sky Park and Observatory is open, with pre-booking, and some restrictions.

 See https://www.midulstercouncil.org/visitor/things-to-do/star-gazing/davagh-dark-sky-observatory , and https://www.facebook.com/omdarksky/ I'll post any updates here. Or phone 03000 132 132 for changing Covid-19 advice.

 

11. EASY TEASER:

What comes up sideways, but goes down vertically? No guesses yet, so - Clue: There's a pair. Another clue: "It's in your stars". Another clue: the coming up starts in the autumn, and the going down happens in the spring. Still no correct answers, so here's a final clue. It's a constellation .

 

12. DIFFICULT TEASER:

What's the connection between: a London Borough, a piece of rock, and another solar system body? No guesses yet, so – Clue: the other solar system body is a planet. Another clue: it's one of the 'terrestrial planets". Another clue: the residents of the borough seem to like using their car horns.

 

  Please send all Teaser answers to me at my aol address terrymosel@aol.com

Total Lunar Eclipse tonight, ISS, Dark skies, IDL, CAP, Light Conf, Parade of Planets, Asteroid Day, On the Moon, more

Hi all,

 

1. TOTAL LUNAR ECLIPSE 16 May. (Times in BST/IST)

More than half of this eclipse is visible from Ireland. The further West and South you are, the better the view, as the Moon sets later there. The penumbral phase, which is barely noticeable, starts at 02.30; the Moon enters the umbra at 03.27, and totality starts at 04.28. Mid eclipse occurs at 05.11, with an umbral magnitude of 1.419. The Moon will pass South of the centre of the Earth's shadow, so the N edge of the Moon should appear a bit darker than the S. edge.  

   The Moon will lie in quite a nice surrounding starfield of red, orange, white and blue 5th and 6th mag stars during totality, giving the possibility of nice wide-field images.

   The Moon will occult 7th mag TYC 6179-152-1 during the partial phase, and a 9.5 mag star, and then an 8.8 mag star during totality, but it will be very low by then. The 7th mag star will reappear from behind the Moon during totality, but just before the moon sets, so it will also be difficult to see. The exact time of the occultations will depend on your location; email me (terrymosel@aol.com) for exact details if you don't have software to check it for yourself. Remember also that as the Moon gets lower, the Sun gets higher, and twilight brightens!

   This table gives the altitude of the Moon in degrees at the start and middle of totality for various locations

Location          Start Totality    Mid-Totality

Belfast                         4.9º      0.6º

L/derry                         5.3       1.0

Dublin                         6.0       1.5

Sligo                            6.3       1.9

Athlone                        6.7       2.2

Wexford                      7.0       2.4

Galway                        7.2       2.7

Limerick                      7.4       2.9

3. Join the 2022 Edition of Dark and Quiet Skies Awareness

In alignment with UNESCO's International Day of Light on 16 May, the IAU Office for Astronomy Outreach is dedicating the entire month of May to Dark and Quiet Skies Awareness. We have a lot of fun activities planned: 
   Celebrate the Dark Skies Drawing Contest
Imagine you've stumbled into an open clearing. It's well past sunset, and the Moon is new - what do you see when you look up at the sky? Are there city lights? Stars? Can you spot any planets? The Milky Way? What do these views mean to you? 
  Using any medium you'd like, create a piece of art that describes what dark skies mean to you and your community. Three submissions will be randomly selected to win a BRESSER NANO AR-70/700 AZ Telescope, courtesy of Sterren Schitteren Voor Iedereen (Stars Shine For Everyone - SSVI). Winners will also have the chance to share their artwork during One Home, One Sky: A Seminar for the Protection of Dark and Quiet Skies (more details below). The deadline to send in artwork is 24 May 2022. For more information on how to participate, eligibility, terms and conditions see this document
  Calendar of Events and Social Media
The IAU OAO and the IAU National Outreach Coordinators (NOCs) participate in various events to raise awareness of the importance of dark and quiet skies. Join an event hosted or supported by one of our 130+ NOCs, IAU Dark Skies Ambassadors or other organisers from the astronomy outreach community around the world. Hosting your own event? Register your event in the Astronomy Outreach Event Calendar. Don't forget to follow the OAO's Facebook and Twitter accounts for updates on upcoming events near you, and look for the hashtags #DarkSkies4All and #IDL2022 to share resources, activities and ways to take action.
  One Sky, One Home: A Seminar for the Protection of Dark and Quiet Skies 
This online event will bring together astronomers, outreach professionals, artists, curators, and practitioners to share their connection to the dark sky, its importance to the world's cultures and to our global ecosystem. We invite the broader astronomy community and all citizens of Earth to engage the problem head-on and discover solutions together. To register for the event, please visit this page.

6. History And Philosophy of Physics; St Cross College, Oxford, 11 June.

ONE-DAY CONFERENCE: "The Nature of Light" - IN PERSON AND LIVESTREAMED ONLINE, on Saturday 11th June from 10.30 am - 5.00 pm BST

    Visible light is the most pervasive feature of the observable Universe to humans, so its explanation has assumed a pre-eminent role in our attempts to understand the physical world around us. This conference will start with an examination of light and its properties with the formulation of the classical theory of optics by Newton, Huygens and others, and then move on to the theory of colours which involved not only natural philosophers, but artists and writers.

   The understanding of electricity and magnetism in the 19th century led ultimately to the formulation of the electromagnetic theory of light summarised in Maxwell's equations which underpin the vast range of technologies still in daily use. In the 20th century, the role of the speed of light became very important in relativity and quantum theory.

  The conference will examine the steps in our understanding of light to illuminate its history in our culture and in the technological developments over the past few decades.

   Registration to attend this conference is free but booking is required to attend the conference with all

the details and the weblinks to register for the conference to attend in person or online given on the

webpage: https://stx.web.ox.ac.uk/event/the-nature-of-light

(This is the College and body where I was honoured to be asked to give a talk on solar eclipses about 5 years ago; It's usually very good!)

 

7. Summer Solstice. The Sun will reach its most Northerly point on the ecliptic on 22 June at 09.13 (10.13 B/IST) marking the start of N. Hemisphere Summer.

 

8. Parade of the Planets, 20 to 28 June

During this period, all the naked eye planets will be visible together in the morning sky, in order of their distance from the Sun, although Mercury will be very low and you'll need binoculars to see it, except perhaps from the very far South of the island. The waning Moon will also be in the area, and on the mornings of 22 to 26 June, the Moon will also be in its correct order from the Sun, i.e. Mercury, Venus, Moon, Mars, Jupiter and Saturn.

Aesthetically, the nicest view will be on the 24th, with the waning crescent Moon about halfway between Venus and Mars.

To find Mercury, look about 10º below left of brilliant Venus, at an angle of about 8p.m. on a clock face. From the N of the island it won't rise until civil twilight has started, and it will be only mag -0.1 on the 24th, -0.2 on the 25th, -0.3 on the 26th, -0.4 on the 27th and -0.5 on the 28th, so binoculars or a wide-field telescope will be required.

   On the 27th, Mercury will lie below the thin crescent Moon, and that will be your last good chance to find Mercury and to be able to see the Moon in the line-up.

Uranus and Neptune will also be in the line, but not in order, and you'll need binoculars or a telescope to see them.

 

9. Asteroid Day, 30 June.

More details later.
