Online telescope clinic, see Mercury and Venus, ISS, Video sky guide, webinar postponed, Vote for astrophoto, New space book, Events and lectures, Teaser answered, more

Hi all,

 

(NB, all times are summer time when in force, for convenience)

 

1. IAA Zoom event, with Armagh Observatory & Planetarium, Wed 26 May, 7.00 p.m .

Online Telescope Clinic. A chance for you to learn all about telescopes, solve any usage problems you may have, and how to use them best, and what to see with them.

   The room will open around 19:15 to allow for a prompt start

This talk will also be Simulcast on our YouTube Channel

https://www.youtube.com/user/irishastronomy/videos

   More details in next bulletin

 

2. Mercury and Venus now visible in evening sky

Mercury is now readily visible, heading for its Greatest Eastern Elongation of 22º 01' on 17 May. Look low in the WNW evening twilight.  On the 13th it will lie 2º 47' to the lower left of the crescent Moon.

The crescent moon will then move on to lie just West of MARS on May 15,

   On the 28th Mercury will be very faint, but it will be joined by much brighter Venus'; at 22.45 that evening Mercury will lie just 29' to the left of Venus. That will be a chance for you to see it as a large diameter but very thin and faint crescent, with a diameter of over 10 arcseconds.

 

3. ISS. The ISS, currently with 9 astronauts on board, started a new series of morning passes on 30 April. These will gradually transition to evening passes, which will then continue until 29 May, so we're getting over 4 weeks of continuous passes!

 

4. Paul Evans has produced his latest excellent sky guide for May

5. SPACE and ASTRONOMY WEBINAR – postponed – more details later

NB: Note platform change. Since most people have been watching on YouTube, we are ceasing the presentation via Zoom, and it will now be streamed live on both YouTube and Facebook. This will also give us lots of added features in the presentation.

After a year of presentations, we're taking a break for April, and we'll be back on  'Star Wars Day' – May the Fourth be with you!

    Presented by me and the amazing Nick Howes, they are approximately 45 minutes long, every second Tuesday, at 7.30 p.m., covering whatever is topical in space and astronomy. The date of the next one will be announced asap: youtube.com/spacestorelive

  NB – So, from now on it will be Live streamed to YouTube SpaceStore Live! Channel and Live streamed to Facebook Live. I'll post any last minute news via Twitter.

 

6. Voting about to close for best astronomy photo competition

Tánaiste Leo Varadkar has launched the online public vote to choose Ireland's best astrophotography images as part of the 'Reach for the Stars' competition.

   'Reach for the Stars' aims to find the best astro-photographs taken in Ireland over the past year. While a high-profile judging panel will select the overall winning entries, an online vote is running over the coming weeks, so members of the public can also have their say.

   During a private visit to DIAS's Dunsink Observatory, the Tánaiste reviewed a number of astro-photographs and officially launched the public vote. Members of the public can now view all images shortlisted for the competition and cast their vote for their favourite via an online gallery on the DIAS website. Over 170 images have been shortlisted this year – the inaugural year of the competition. The winning images selected by the judging panel and the public vote will be announced towards the end of May, and an outdoor exhibition will be staged by DIAS to showcase the best images.

   Voting closes on 09th May 2021 at 23:59 (Irish Summer Time).

You may only vote once.

All votes cast will need to be verified via an email confirmation. Votes that are not verified will not be counted.

For some very sensitive SPAM filters, the verification email may be detoured to your SPAM folder, so please check there just in case it doesn't appear when you think it should.

Thank you for participating!

To cast your vote, visit here: https://www.dias.ie/astrophotography-competition-public.../

    Since quite a few friends have entered photos for this competition, I have to stay neutral, but do have a look and cast your vote asap. Good luck to all! You can also try

13. TEASERS

Easy Teaser – Answers:

Q. Of the 12 official zodiacal constellations, what record is held by Scorpius? The answer was that Scorpius has the shortest length of the ecliptic passing through it, and therefore the Sun spends less time in Scorpius than in any other Zodiacal Constellation.

Two 'experts' answered it (Brian Beesley and Peter Millar), but the first correct answer from an eligible candidate was from Ross Currie, at his first attempt! Well done Ross!

OOPS – Sorry – I also got a correct answer from Colin Parkes – apologies to Collin!

 

HARD TEASER – Answered at last!

The question was - What connects – the Queen's Fiancetto, The Ark, Oscar, Lancaster, a singular lens, and an old British coin?

First correct answer came from CONN BUCKLEY, and a day later, regular winner PETER MILLAR also got it right. The answer is 'Sir Patrick Moore'. Well done to both.

   Patrick was an excellent chess player (he taught me, on cloudy nights in his study in Armagh), and his standard opening move was the Queen's Fiancetto; The Ark was the nickname he gave to his ancient upright Ford Prefect (in which I drove him from Armagh to Birr to meet Lord Rosse, and set in train the restoration of the Leviathan); Oscar was his nickname for his then favourite telescope, a 12.5" Newtonian; Lancaster was the type of bomber in which he flew as a Navigator for the RAF; a 'singular lens' was the monocle which he often wore; and an 'old British coin' was the clue for "Farthings", the name of the house he bought in Selsey when he left Armagh, and where he lived for the rest of his life (and where I visited many times, and observed with his latest telescope, a lovely wooden-tubed long-focus equatorial 15" Newtonian).

New Easy Teaser

What's the connection between – A type of singing, a Keeper of the Mint, a German musician, and a Buddhist monk?

"Rules for Easy Teasers: you're barred from entering if you (A) have already submitted a correct answer to any of the previous teasers, and/or (B) if you've been a member of any astronomy clubs or societies for 15 years or more. Obviously I have to trust your honesty on that latter point, but remember, if you're correct your name will be published here, and other members of your club will see it!"
