Members trip to the South Downs Planetarium & Science Centre – 4th August 2024

On Sunday 4th August 2024 several CMHASD members went on a trip the South Downs Planetarium & Science Centre.  Below is an account of the day kindly written by member Gary Hunt with photos taken by members.

 

''With the decision by the membership to arrange an away-trip, long-term CMHASD friend and lecturer, Dr John Mason MBE, made a gracious offer host our visit to the recently renovated South Downs Planetarium.
 
Little did we know that CMHASD would be the FIRST to see the fully renovated centre and planetarium… I think it demonstrates, just how respected CMHASD is by the community. We are all very grateful to John, who was the consummate host and expert lecturer, and made ALL feel valued and welcome!
 
The membership, began the day by meeting for a wonderful lunch at the Cricketers at Duncton near Chichester. The pub has a stunning garden, and we had drinks there until we were called to our exclusive dining room. We were all delighted, to greet Dr. John Mason and his lovely wife Jane, at the pub and share lunch with them.
 
 
During a delicious repast, some of us sampled some good ales, we made our way to the Sir Patrick Moore Building, based in the grounds of Kingsham Farm, High School, where we were all greeted once again by by John.
 
 
 
After a brief introduction to the brand-new entrance and foyer, replenished with a souvenir shop, and display area. This was overseen by a life-size and frighteningly accurate wax-work of Sir Patrick Moore, supplied by Madame Tussauds, his personal desk, chair, brass telescope (his first brought by his mother when a child), typewriter and desk objet d'art… This was supplemented by numerous astronomical telescopes and instruments, and the beginnings or a multimedia projection system in the high-vaulted hall leading to the planetarium. This area was crowned with a three-metre diameter Moon… spectacular, indeed!
 
 
 
 
We were then all ushered into a lecture area and told more about the Centre, by the delightful and very hardworking, Meryl Goulbourne, what a credit she is to the Centre. The news included a recent award gifted by King Charles III. Following this we were escorted to the Planetarium itself for an hour long, tour de force presentation on the mysteries of Dark Matter by John himself.
 
John certainly knew his stuff… But before we got to the main subject, John took us through the amazing simulation of the night sky as it would be later that night in Chichester, then Selsey (Sir Patrick’s home town), and the dark skies park of the South Downs. This was followed by looking at constellations as we headed via the equator until we were observing the Southern Hemisphere (e.g. New Zealand)
 
 
As we then moved onto the mind-boggling issue of Dark Matter, and it’s effect on deep space objects, we were regaled with the latest technical news of how astronomers are trying to prove that Dark Matter exists? I was amazed at just how knowledgeable John is, particularly as he was presenting from memory, and proven by just how dark it was in the planetarium!
 
 
As the presentation ended, it then came to a Q&A session, needless to say that John had made his presentation so complete, that there wasn’t much CMHASD members could ‘try to catch him out on’ 😆! A superb lecture, that the membership was privileged to witness. But that wasn’t all… John then proceeded to answer technical questions about the Planetarium dome, its structure and construction… followed by an high-end engineering standard of knowledge regarding the Viewlex-Minolta S-IIb star projector and its other video adaptions… Even a mention about the (far to comfortable!) club class airliner seating (still with ashtrays in situ)!
 
 
All CMHASD members were very grateful for such an outstanding presentation, and warm hosting by John, Meryl and the staff.
 
There followed refreshments and discussion, for an hour or so thereafter… wonderful company, and a wonderful experience.
 
I have no hesitation in recommending a visit, for newbies or experienced astronomers, alike, or indeed, a revisit to the South Downs Planetarium and Science Centre…. Not only well worth supporting to keep it going, but to highlight a very bright star in heart of Sussex!
 
and finally, I would like to say a very big Thank you to Rita Whiting for organising such a wonderful trip.  It was superb!''

1st August 2024 – Thunderhead

As Astronomers we observe weather conditions regularly and on the 1st August 2024 a stunning time-lapse video was taken by member Honor Wheeler of a Thunderhead.  The video was taken from Dartford.  A thunderhead is a cumulonimbus cloud seen during a thunderstorm.  Towering cumulonimbus clouds, often called thunderclouds, are the only cloud formation capable of generating hail, thunder, and lightning. These dramatic, multi-layered cloud structures extend high into the sky, taking on an ominous, menacing appearance.

Honor used a Canon M6II on a tripod, Rokinon 12mm lens, at f/8, ISO400. A total of 300 photos with a 5 sec interval.

Summer Solstice Sun – 20th June 2024

NEVER LOOK AT THE SUN DIRECTLY. Please click here for solar observing safely.

A fantastic photo of our Sun as it set taken by member Honor Wheeler from Weybourne Beach, Norfolk on the 20th June 2024.  Massive sunspots can be seen at the 5 O'Clock position on the Sun. This image will also be found in the July edition of 'The Astronomer'. Well done Honor; it is indeed a super image.

 

 

Earlier in the day on the 20th Dr Mike Rushton took this great image of the Sun using his Dwarf II smartscope.

Below for comparison; is a screenshot of the Sun on the 20th June 2024 with the Sunspots numbered taken from Spaceweather.com

 

Then on the day after; on the 21st member Jim Burchell took this superb image of the Sun.

 

 

The latest ExoClock project transits

Martin Crow and Simon Dawes have been busy taking more measurements of Exoplanet transits for the ExoClock project.  Below are some of their latest ones.

''TrES-2b (also known as Kepler-1b or GSC 03549-02811b) is an extrasolar planet orbiting the star GSC 03549-02811 located 750 light years away from the Solar System in Draco. The planet was identified in 2011 as the darkest known exoplanet, reflecting less than 1% of any light that hits it. Reflecting less light than charcoal, on the surface the planet is said to be pitch black.  The planet's mass and radius indicate that it is a gas giant with a bulk composition similar to that of Jupiter. Unlike Jupiter, but similar to many planets detected around other stars, TrES-2b is located very close to its star and belongs to the class of planets known as hot Jupiters. This system was within the field of view of the Kepler spacecraft.  It was discovered on August 21, 2006 by the Trans-Atlantic Exoplanet Survey (TrES) by detecting the transit of the planet across its parent star using Sleuth (Palomar Observatory, California) and PSST (Lowell Observatory, Arizona), part of the TrES network of 10–cm telescopes. The discovery was confirmed by the W. M. Keck Observatory on September 8, 2006, by measuring the radial velocity of the star that hosts TrES-2b.'' Ref:https://en.wikipedia.org/wiki/TrES-2b

 

HAT-P-37b is an exoplanet in the constellation Draco.

''HAT-P-37 b is a gas giant exoplanet that orbits a G-type star. Its mass is 1.169 Jupiters, it takes 2.8 days to complete one orbit of its star, and is 0.0379 AU from its star. Its discovery was announced in 2011.'' Ref:https://science.nasa.gov/exoplanet-catalog/hat-p-37-b/

 

''Qatar-4b is a super-jupiter orbiting the star Qatar-4 every 1.8 days in Andromeda. It was discovered in 2016 by the Qatar Exoplanet Survey (QES).

This planet has a very short orbit, with only 1.8 days for it to complete an orbit around Qatar-4. The period corresponds with a separation of around 0.03 AU, which is almost 20 times closer than Mercury is to the Sun. Despite that, it has a perfectly round orbit. Since the host is an active star, Qatar-4 may be destroyed by tidal waves from the star.'' Ref:https://en.wikipedia.org/wiki/Qatar-4b

 

''TrES-3b is an extrasolar planet orbiting the star GSC 03089-00929. It has an orbital period of just 31 hours and nearly twice the mass of Jupiter.

The planet TrES-3b is named Umbäässa. The name was selected in the NameExoWorlds campaign by Liechtenstein, during the 100th anniversary of the IAU. In the local dialect of southern Liechtenstein, Umbäässa is a small and barely visible ant.

It is the third transiting planet found by the Trans-Atlantic Exoplanet Survey. It was discovered in the constellation Hercules about 10 degrees west of Vega.'' Ref:https://en.wikipedia.org/wiki/TrES-3b
