Hi all,

 

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

 

1, IAA lecture via Zoom & YouTube, 17 March, 7.30 p.m.: " Messier: The Man and His Legacy by John Flannery, IAS

Abstract: Two hundred and fifty years ago this year the French astronomer Charles Messier (1730-1817) submitted the first draft of a catalogue that would guarantee him lasting fame. Now recognised as a list of the sky's showpiece objects, it contains highlights such as the Great Nebula in Orion (designated M42); the Andromeda Galaxy (M31); and the beautiful Pleiades star cluster (M45). Tonight's talk by Irish Astronomical Society member John Flannery will tell a little about the life of Charles Messier, how his catalogue came into being, and its importance in astronomy.

Biography  John needs no introduction to anyone in the field of Irish Amateur astronomy; he can truly be described as one of the stalwarts. We're delighted to have him give another talk to us.

   He is editor of the IAS quarterly journal; he writes a monthly night sky column for the Irish Times, and is active in various forms of astronomy outreach. His main interests as an amateur astronomer are the sky lore of world cultures; binocular observing; and astronomical history.

Time: Mar 17, 2021 07:15 PM London

4. REGULAR FORTNIGHTLY SPACE and ASTRONOMY WEBINAR – Next is March 23

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.

    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 next one will be on Tuesday 23 February: 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.

 

5. Dara O'Briain joins AOP to talk about the world-famous NGC, which was compiled at Armagh Observatory on 24 March, tickets on sale on 15 March https://www.facebook.com/groups/irishastro/permalink/10159885718470955/?sfnsn=scwspmo

 

6. STAR TRACKER ONLINE, hosted by AOP,   31 Mar.

Armagh Observatory and Planetarium hosts "Armagh StarTracker Online", a star show where we take you on a tour of the night sky using a virtual planetarium followed by live viewing the stars using telescopes in the Canary Islands. We will be using Slooh's online robotic telescopes to view the celestial objects. There will be a chance throughout the sessions to ask questions to the Director of Armagh Observatory and Planetarium, Professor Michael Burton.
    Each session will focus on different objects and stars that are visible in the night sky.
    Tickets are free (donations are welcome) and the zoom details will be emailed in advance.
*Please note you only need to book one ticket for one household.*

Date: 31st March, Time: 8pm
Admission: Free (donations welcome)

13. Easy Teaser: Of the 12 official zodiacal constellations, what record is held by Scorpius?

 I forgot to repeat the rules for that, but they are: 

"Rules: 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!"

  There has only been one correct answer so far, but that was from someone who is not eligible under the rules above.

 

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

 

14. Close fast pass by mountain-sized asteroid on March 21.

Asteroid 231937 will whizz past us on Mar 21, at only 5.3 Lunar Distances, and at the high speed of 34.4km/sec. It has an estimated diameter of 1024m. No danger of a collision, but that's fairly close for such a big asteroid and especially one going so fast! Remember, the energy of the impact increases directly with the mass of the body, but increases with the square of the velocity.  That impact would destroy everything in an area the size of Ireland

UPDATE: Of the 60 NEOs listed currently on Space.com (at the time of writing), this one has BY FAR the highest relative velocity! The mean velocity of those 60 is 10.26 km/sec. And the next highest velocity after this one is 26km/sec, and that's for a much smaller body and at a much greater distance.

   And it's more than twice the diameter of the next biggest one in the list! In fact, so it's more than 8 times larger in volume, and it's almost 17 times larger in diameter than the average on that list.

   And you thought that Betelgeuse was big??? Hubble solves mystery of monster star's dimming (phys.org)  You can see this amazing star yourself with a small telescope. It's about mag 8, but varies between mag 6.5 to 9.6. It lies about 1 deg 15' SE of Tau CMa, at RA 7h 23m 20s, and Dec -25 deg 47' 10". That's quite far South so you'll need a good clear horizon to the South. It's very red, but the colour will only show up in larger telescopes, unless it's near maximum.
