IAA lecture, Venus and Jupiter, ISS, Total Lunar Eclipse, 100 hrs of astronomy

Hi all,

 

1.  IAA New Year Lecture and demo, 9 Jan: 'Everything you wanted to know about Telescopes'.. By Dr Andy McCrea (thanks to Andy for standing in at short notice). Andy needs no introduction: as proprietor of North Down Telescopes, for many years he has been supplying amateur and professional astronomers throughout Ireland with all sorts of astronomical equipment from a complete observatory down to an eyepiece or filter. He's also an accomplished astro-imager, with many excellent photos in Stardust and our exhibitions to his credit. If there's anything he doesn't know about telescopes, binoculars and astrophotography, it's not worth knowing!

   He has agreed to step in at short notice as another speaker had other last minute commitments. He'll bring along a selection of equipment, as well as telling you all you need to know.

Bell Lecture Theatre, Physics Building , QUB, 7.30pm

All welcome. Free admission, including light refreshments.

 

2. Venus and Jupiter in the morning sky. Brilliant Venus is still easily visible in the morning sky, with fainter (but still bright) Jupiter lower down in the twilight, but the distance between them is gradually decreasing. Venus will pass less than 3 degrees above Jupiter on Jan 21 and 22, so look out for that nice pairing after the Total Lunar Eclipse on Jan 21 – see below.

 

3. ISS. The ISS continues its series of morning passes until 10 January. It will then commence a new series of evening passes on 23 January Details for your own location, and lots more info on space and astronomy, on www.heavens-above.com.

4. Participate in the 100 Hours of Astronomy Global Project, Jan 10 - 13.
In 2019, the International Astronomical Union (IAU) will celebrate its 100th anniversary (IAU100) and to commemorate, we will organise a year-long celebration to increase awareness of a century of astronomical discoveries as well as to support and improve the use of astronomy as a tool for education, development and diplomacy.
   The
100 Hours of Astronomy will be the kick-off worldwide event of IAU100 and will be composed of a broad range of activities aimed at involving the public. 100 Hours of Astronomy will take place over four days and nights, from 10-13 January 2019, with amateur and professional astronomers, astronomy enthusiasts and the general public invited to share their knowledge and enthusiasm for the Universe. Hundreds of local events are being planned by science facilities and astronomy enthusiasts around the world, including telescope observing sessions, exhibitions, lectures, art projects, classroom projects, field trips, special shows and more. In many countries, there will be public lectures by specially selected speakers, experts in astronomy, keen to participate in this planet-wide venture.
   It is only a few months before the yearlong centennial celebration of the International Astronomical Union (IAU) will take place. As a big kick-off event, the global project 100 Hours of Astronomy is organised to take place 10-13 January 2019. Everyone around the globe can participate in this joint effort to bring astronomy to the general public.

5. NEW Total Lunar Eclipse, 21 January.

This is the first TLE to be entirely visible from Ireland since 28 Sep 2015. The next one where totality is partly visible from here will be on 16 May, 2022, but it sets during totality. The next good one will be on 31 Dec 2028, when the Moon is 1.5º up at the start of totality. Believe it or not, the next TLE which is entirely visible from here won't be until 20 Dec 2029! So let's hope for a clear night, and make the most of it since it's a long time to the next one!

   This is quite a long eclipse, with an umbral magnitude of 1.201, and 1h 3m of totality. The moon will be quite high up for all the major stages of the eclipse – 48º at the start, and down to 14º at the end of the umbral stage. It will still be 6º up at the very end of the penumbral stage. First contact of the penumbra is at a PA of 110.5º, and of the umbra at 118º, which is about SSE on the Moon's disc. The Moon will pass North of the centre of the Earth's shadow; in fact no part of the moon will actually pass through the centre of our shadow.

   The Moon will occult only one moderately bright star during totality: Tyc 1385-873-1, mag 8.5, at about 04h 33m (look several minutes before this time, or up to 10 mts earlier if you are in the far W of the island.

   One of the interesting things abojt TLEs is that no-one knows in advance just what they will look like. The moon can turn anywhere from a bright orange-red to a deep almost crimson/grey red: it all depends on the amount of dust and dirt and aerosols in our upper atmosphere, through which sunlight passes to reach the Moon.

 

Moon enters penumbra 02h 34m 43s

Moon enters umbra 03h 33m 16s

Start of totality 04h 40m 30s

Maximum eclipse 05h 11m 59s

End of totality 05h 43m 30s

Moon leaves umbra 06h 50m 44s

Moon leaves penumbra 07h 49m 15s

 

6. The Galway Astronomy Festival takes place on Saturday January 26th, 2019. The festival will take place in the new venue, The Harbour Hotel, New Docks Road, Galway.

Last year's festival went well, and hopefully this coming year's festival will be equally successful.

 

7.  International Day of Women in Science / Women and Girls in Astronomy Day 11 Feb

The International Day of Women and Girls in Science is celebrated each year on 11 February and was adopted by the United Nations to promote full and equal access to and participation in science for women and girls. This Day is a reminder that women and girls play a critical role in science and technology communities and that their participation should be strengthened.

The IAU100 strongly encourages the organization of activities throughout 2019, especially events organised around February as the perfect opportunity to celebrate girls and women in astronomy - by encouraging girls to consider careers in astronomy and by celebrating women astronomers. We encourage everyone to get involved with the Women and Girls in Astronomy Day by running events in your local community. This can include public talks, activities, workshops, and more.  

   Under the theme "Inclusive Astronomy" the IAU100 celebrations will organise a wide array of global activities and events throughout the year to promote inclusivity, equity, and diversity in astronomy. These events will kick off around 11 February 2019 with the celebration of the IAU100 Women and Girls in Astronomy Day within the framework of the United Nations' International Day of Women and Girls in Science. This is the perfect opportunity to celebrate girls and women in astronomy by encouraging girls to consider careers in astronomy and by celebrating women astronomers. We encourage everyone to get involved with the Women and Girls in Astronomy Day by running events in your local community.

Happy New Year



Hi all,

 

UPDATE

Firstly, Happy New Year to everyone. And apologies for not being able to wish you all Happy Xmas etc in time, and indeed for the long gap since my last bulletin. It's a long story, but basically because of changes in AOL I was no longer able to send multiple copies of my bulletin, so after a long period of struggle I changed to a new gmail account. Unfortunately even that will not allow me to send bulk emailings, but it won't tell me which addresses have received the last bulletin, and which have not!

   So, apologies if you have already received this one – although I have updated it slightly for this latest attempt, where I will try to send it in much smaller batches.

  So in the meantime I'll still be using both accounts, until I manage to get the new email sorted, and notify everyone of the change.

Please also note change of next lecture!

 

HAPPY NEW YEAR to all!

 

1. IAA New Year Party, 5 January – Book by 3 January.

The astrosocial event of the year will be held once again at McBrides in Comber, followed by the excellent film "Moonwalk One" and team quiz in the Tudor Private cinema nearby. You can book online at www.irishastro.org.

3. Venus, Jupiter and Mercury in the morning sky. Brilliant Venus is still easily visible in the morning sky, with fainter (but still bright) Jupiter lower down in the twilight, and Mercury fainter and lower still, and getting more difficult to see as it dips closer to the horizon. On 3-4 January the group is joined by a waning crescent Moon, providing a lovely photo opportunity. On Jan 3, the Moon lies close to Jupiter, the middle of the trio.

 

4. ISS. The ISS continues its series of morning passes until 10 January. Details for your own location, and lots more info on space and astronomy, on www.heavens-above.com

6. Earth at Perihelion on Jan 3d 5h 19m. The Sun has its largest apparent diameter as we see it, of 32' 32", on that date.

 

7. Quadrantid Meteors. This shower will peak on the night of 3-4 January. The Moon will be out of the way, giving dark sky if it's clear. The radiant is circumpolar from Ireland, so meteors can be seen any time after the sky gets dark, but best rates will be seen later in the night, as it gets higher up. It lies about halfway between the end of the handle of the Plough / Big Dipper and the head of Draco. In a dark sky with the radiant highest you could see rates of 60 per hour or more.

 

8.  "Under One Sky" Short Story Competition is Launched
We are pleased to invite astronomy students worldwide to take part in the IAU100 "Under One Sky" writing contest. The IAU values the engagement of young scientists in its activities and this competition is aimed at stimulating astronomy students' creativity and imagination by soliciting short written stories related to the themes 'Under One Sky' and 'Inspiring Stars'. Participants will get a chance to attend the IAU100 Flagship event in Brussels, Belgium. The IAU100 Under One Sky Event will take place at the Palace of the Academies in Brussels (Belgium) on 11-13 April 2019.

9. Armagh Planetarium: "Mystery of the Christmas Star" Dome Show now showing.

Join Armagh Planetarium this Christmas as we journey back more than 2000 years to Bethlehem, and seek to discover an explanation for the star the Wise Men followed to find the baby Jesus in "Mystery of the Christmas Star".  
   The Star of Bethlehem is an iconic astronomical event whose true origin remains unknown even today, in spite of years of speculation and research. The show will guide the viewer through some of these investigations and the most likely causes of this interesting cosmological object which was remarkable enough to make the wise men travel across the desert from Babylon to Bethlehem to see the newborn baby.  You will also explore possible dates for the birth of Christ and look at the historical records of significant astronomical events which occurred at this time.  This modern retelling of the Christmas story in our digital theatre will charm and captivate audiences.

The show runs until Saturday 5th January 2019.

Show Times:

Tuesday – Friday at 2pm

Saturday/School Holidays at 2pm and 4pm
