Hi all,
1. Season's Greetings to all. And a very Happy New Year.
2. ISS. A new series of morning passes over Ireland will commence on 28 December. Details for your own location, along with lots more information such as Iridium Flares, at www.heavens-above.com
3. Lunar Occultations – we get a nice series ending December:
On 28 Dec the waxing gibbous moon occults Xi2 Cet. Disappearance will be at 19.16.
On 29 Dec it will occult 5 Tau (mag 4.1) at about 22.45.
30-31 December. Ending the year in style, it occults 5 stars in the Hyades, culminating with Aldebaran! First will be Gamma Tau (mag 3.6), at 17.08 on Dec 30; in twilight, with the Sun 8.2 degrees below the horizon, but visible in binoculars. Next, at 19.48, will be 70 Tau (mag 6.5). At 21.15 it will be the turn of 75 Tau (mag 5.0). That will be followed at 22.24 by HIP 21029 (mag 4.8). Finally, to see in New Year's Day, it will occult Aldebaran (mag 0.8) at 01.02, with reappearance at 01.55.
In every case the event will be instantaneous: the star will literally disappear or reappear in a tiny fraction of a second, so it really is a case of 'blink and you'll miss it'. It's a nice proof that almost all stars really are just point sources of light, as seen from distances of many light years.
Look up to about 10 minutes earlier than those times to be safe.
4. Mars- Jupiter Conjunction
On 1 January Mars lies only 2º 40' to the right of, and a bit above, much brighter Jupiter: Mars will be mag +1.5, whereas Jupiter will be -1.8. Over the next few days the separation decreases until on 6 Jan Mars will be only 23' to the right of Jupiter. Next morning just after they rise Mars will be only 13' below and a bit right of Jupiter – that's less than half a Moon diameter. Next morning the separation will have increased to 35' – a bit more than a Moon diameter.
5. Full Moons: The first of two Full Moons in January will be on the 2nd on 02h 24m; the second will be on Jan 31d 13h 26m, - and it won't be a 'Blue Moon'!
6. Earth at Perihelion. Earth will be at its closest to the Sun in its elliptical orbit on January 03 at 05.34, at a distance of 0.9833 AU.
7. Quadrantid Meteors, Jan 3-4. This shower will peak on the night of Jan 3-4, but unfortunately the Moon will be just past full, and will drown out all but the brighter meteors. The radiant, in the now defunct constellation of Quadrans Muralis, lies about halfway between the last star in the handle of the Plough and the head of Draco. It's circumpolar from Ireland, and especially from the N part of the island, it's high enough to give us a few meteors before the Moon rises at about 18.30. After moonrise, position yourself where the Moon is hidden behind a building or similar, and look away from that area of the sky.
8. IAA New Year Party: 6. January 2018, at McBride's on the Square, Comber, Co. Down. We start off with buffet eats and drinks at McBride's, at 5.15 for 5.30 p.m.; then make our way to the Tudor Private Cinema about a mile away, for more seasonal hot drinks, a special showing of "Hidden Figures" (highly recommended), and the usual quiz for all. Details are on the IAA website, and a booking form will be issued with the latest Stardust which will soon be sent to IAA members. All are welcome, including guests and non-members.
9. Next IAA LECTURE, Wed 10 January, 7.30 p.m. "Einstein made (relatively) Simple." By Brian MacGabhann. More details later.
Wed 10 January, 7.30 p.m., Bell Lecture Theatre, Physics Building, QUB. Free admission, including light refreshments. Free parking on QUB campus after 5.30 p.m.
10. IAA Photo Exhibition, Carrickfergus Our very successful photo exhibition continues at its latest venue, Carrickfergus Museum and Civic Centre, until 6 January. Be sure to watch the excellent video display of some recent aurorae and other phenomena such as eclipses and conjunctions. Also on display are various antique telescopes and other astronomical equipment on loan from Armagh Observatory and Planetarium and myself, and some space items on loan from Dr Andy McCrea. It continues there until 6 January.
For further information please contact Carrickfergus Museum, T: 028 9335 8241 or E: carrickfergusmuseums@
11. COSMIC CONNECTIONS EXHIBITION, Dungannon, 2-29 December.
IAA member Martin Campbell from Dungannon will be exhibiting some of his excellent astronomy photos at
Ranfurly House Arts and Visitors Centre, 26 Market St, Dungannon, BT70 1AB, from December 2 to December 29 2017. Open 9.00 – 17.00. Admission Free.
12. Eclipse Megamovie Citizen Science Project. The Eclipse Megamovie Project, a first-of-its-kind citizen science effort that brought together thousands of volunteers across the United States to capture the August 2017 total solar eclipse, received over 60,000 images! We've been pouring through them and thinking about all the different ways we can take this project to the next level. As a result, we've launched a brand new online citizen science project that is open to anyone, anywhere in the world with an Internet connection to get involved in our on-going scientific investigation. Curious? We hope so! Here's how you can participate:
Megamovie Maestros I on Zooniverse
In this first of multiple Zooniverse projects yet to come, you will help us determine what our volunteers actually captured by identifying eclipse phases and other phenomenon of interest. You will be shown images one at a time from the Eclipse Megamovie image database. For each image, we will ask you what you see. A tutorial and help link make choosing your answers fairly simple. You can also "Talk" to discuss the images in more detail with our team and other project participants. Plus it's a great way to relive the eclipse and see some stunning eclipse imagery, thanks to our oh-so-talented volunteer photographers! You will even occasionally see a photo of our volunteers themselves (if they uploaded any selfies), which helps make the project fun to do too.

13. NASA invites names for next New Horizons target body.
See http://www.frontierworlds.org/ and
https://www.aol.co.uk/video/
But seriously, how about a campaign from all Irish astronomers to have it named 'Edgeworth', after Kenneth Edgeworth of Streete, Co Westmeath, who predicted the existence of the large group of small bodies in the outer solar system, of which this body is one. The accepted name for this band of smallish bodies is the Kuiper Belt, named after the Dutch-American astronomer who later gave it more publicity. However many local astronomers refer to it as the Edgeworth-Kuiper Belt. We are unlikely to get the accepted name for the KB changed, but naming this particular object after Edgeworth would give some long-overdue recognition to a noted local astronomer. So if you agree, vote Edgeworth, and pass it on!

14. IFAS Calendars – UPDATE: I have now got copies of the 2018 edition of these calendars for those who ordered them via me. I'll bring them to the meeting on 10 January.
15. ESO launches new Virtual Reality Tours to experience its sites
ESO's Virtual Tours are a collection of hundreds of 360-degree panorama pictures that can be used for many purposes. ESO's latest release includes options to view the images in virtual reality mode or 360-degree panoramic mode. You can now use a cell phone with either a standard cardboard virtual reality headset or oculus rift glasses to experience tours of ESO's facilities in an exciting new way. This latest release also includes new and updated virtual tours of ESO's observatories and facilities, bringing better functionality on computers and new panoramic views.
