CMHASD supporting the BAA at New Scientist Live 2022

Crayford Manor House Astronomical Society Dartford (CMHASD) were out in force at the recent New Scientist Live event at ExCel Centre, London Docklands on the 7th to 9th October 2022.  We were there to help the British Astronomical Association (BAA), in which we have many members; on their stand in the Cosmos Section this year.  

Everybody pitched in; helping the BAA team organised by CMHASD member Janice McClean who is a trustee and the Events Coordinator of the BAA to promote membership of the BAA and answer questions ranging from 'What type of telescope should I buy?' to 'How do you use a Planisphere?'

Janice said ''After three years closure, it was great to be back.''

A big Thank you to CMHASD members Steve Floodgate & David Grist (our own Eric and Ernie) who were there for all three days of the event with Janice together with Mark Radice from Basingstoke Astronomical Society. 

Thanks fully to CMHASD members Rita Whiting and Debra Holton who were there to keep the peace on Friday (School’s day) and to CMHASD member Diane Clarke who got pulled in after rashly accepting a guest pass when the sheer number of visitors became overwhelming.  CMHASD trustee Mike Rushton added some calm and gravitas to the mayhem on Saturday and Rita returned on Sunday for even more!

 

Anita and Tinie the societies Dobsonian telescopes were the favourites with all the visitors. 
 
 
It was worked out that approximately 1200 people had a look through Tinie at Jupiter - a hand painted 3D printed scale model that was ''Cunningly positioned on top of the biggest combine harvester you ever saw.  Thank goodness the threshing bar wasn’t attached.'' said Janice.
 
 
 
 
 
 
The BAA sold several hundred pounds worth of moon maps, beginners books and observation guides too.
 
''Have we got the stamina for next year?'' asked Janice to which she also replied ''Hopefully the Crayford ‘A’ Team will not be put off by all the hard work but attracted to the odd free beverage provided by the organisers!'' 
 
 
Thankyou to Mike, Janice and Diane for sharing your photographs with us and to Janice & Diane for their help writing this post.
 

Neil Webster’s latest deep sky image of Sadr and music video titled ‘Pickering’s Triangle’.

Member Neil Webster has been busy..........

This is the latest stunning deep sky image by Neil of Hydrogen Alpha nebulosity surrounding the star Gamma Cygni (Sadr) taken on the 20th October 2022. 

Neil acquired the image using a AA 115mmAPO, EQ6 R, ZWO ASI294MC Pro, Optolong L enhance filter, Orion 50mm Guide Scope and ZWO ASI290MM.

47 x 240s lights, 12 x Darks, 35 x flats/bias.

Sadr, Gamma Cygni (γ Cyg) is a yellow-white supergiant star located in the constellation Cygnus. Sadr is the constellation’s second brightest star after Deneb with an apparent magnitude of 2.23. It is the star forming the intersection of an asterism of five stars called the Northern Cross an asterism that dominates the summer sky in the northern hemisphere. Sadr lies in a rich field of the Milky Way and is surrounded by the diffuse emission nebula IC1318 also known as the Gamma Cygni Nebula or Sadr Region. 

Plus hot off the press today - the latest music video created by Neil titled Pickering's Triangle.  Take a trip round Pickering's Triangle in Cygnus imaged by Neil to a pulsey soundtrack and seriously wayward piano near the end.

Exoplanets WASP-114b and Qatar-5b observations by Simon Dawes

Two more sets of exoplanet observations for the ExoClock project by member Simon Dawes of WASP-114b and Qatar-5b.  These are the 56th and 57th set of observations Simon has completed for the project.

WASP-114b is a Hot Jupiter in a 1.5-day orbit around a G0 star.

 

Qatar-5b is a Hot Jupiter orbiting the star Qatar-5 located in Andromeda constellation.  It orbits its star every 2.87 days. It was discovered in 2016 by the Qatar Exoplanet Survey (QES).

Cosmic Camp 2022

Several society members attended Shears Green Junior School on Friday 23rd September 2022 with their own or a society telescope to take part in the school's ‘Cosmic Camp’. 

Below are 2 accounts of the evening by CMHASD members Diane Clarke and Gary Hunt who both helped at the event.

Diane wrote ''The Society was invited for its second visit to the “Cosmic Camp” at Shears Green Junior School  on Friday the 23rd of September.  Several members were present, bringing 5 telescopes including Anita & Isaac, 2 of the Societies “Dobs”.

When we arrived we were enthusiastically greeted by several of the campers in spite of the somewhat overcast conditions that never dampened their spirits.  So we decided to persevere and set up our telescopes with an initial idea of focusing on various cranes & other industrial architecture along a distant horizon to give the campers something to see through the eyepiece.  All the while hoping the sky would clear.

Eventually the clouds started to break initially giving views of Altair & Deneb,  two of the stars that form the asterism known as the “summer triangle”.  As the cloud continued to break the campers were treated to views of Jupiter & its 4 main Galilean Moons through our telescopes.  Unlike last year there was no Moon and unfortunately the clouds did not break enough for us to offer the campers views of the planets Saturn or Mars.

Apart from having the 5 telescopes present we also gave 3 indoor presentations, these included showing the campers some astronomical images taken by the members, along with talks and demonstrations covering both the solar system & the constellations.

The campers had also been learning about the ISS and a visible Pass was expected so with great anticipation we gathered the camper’s together as the clouds broke enabling them to see the ISS that was greeted with a resounding cheer as it passed overhead.  This was a very enjoyable evening for members & campers alike so much so that yet again we stayed longer than expected.''

Gary wrote “From a personal point of view and as an enthusiastic member of Crayford Manor House Astronomical Society Dartford (CMHASD), I found the experience of helping the young students of Shears Green Primary School see the night sky very rewarding. This night was Shears Green’s annual Cosmic Camp and CMHASD was very happy to help again (we helped out last year), as we love to share our fascination of astronomy and all things space! Most CMHASD members have started our fascination with astronomy at an early age and we are committed to inspire young minds to look into the night sky and wonder just like we did many years ago.

 Last years event had clear night skies, sadly this year was mostly cloudy, but fortunately no rain. However, there were the occasional gaps in the clouds that allowed us to show some of the children Jupiter and some of its moons. We were also fortunate enough to show the children the International Space Station passing high overhead, the resulting cheers and screams of delight were deafening! Some CMHASD members also gave talks and educational games indoors to the children which were very well received.
 
The staff of Shears Green were very welcoming and enthusiastic, with themselves peering though our telescopes (including our Dobsonian telescopes Issac and Anita) and asking astronomical questions… we hope they enjoyed it as much as we did, especially as some of them were to stay with the children for the rest of the night in their outdoor camp!  We enjoyed our visit and if there is another Shears Green Cosmic Camp next year we will be pleased to be asked to attend again I am sure!” 
 

The Society did not take any photos of the event as there were too many safeguarding issues however the school blog hopefully will post some photos soon as they did with Cosmic Camp 2021 https://www.shearsgreenjuniorschool.co.uk/cosmic-camp-2021/- so do keep checking.

The Society would like to say a big Thank you to all the members who helped make this event a success.

Sun Pillar by John Archer

CMHASD Chairman John Archer captured a beautiful sunrise on the morning of the 12th October 2022 along with an atmospheric phenomenon called a 'sun pillar' albeit a small one. 

'A sun pillar is a vertical streak of light that appears above or below a low Sun that is shining through ice-crystal clouds, such as Cirrus, Cirrostratus and Cirrocumulus, or the ground-level ice-crystal fog, diamond dust.' https://cloudappreciationsociety.org/cloud-library/sun-pillar/

They can be 5 to 10 degrees tall and sometimes even higher. They might lengthen or brighten as you gaze at them.

The Hunter’s Moon – 9th October 2022

Members Jim Burchell, John Howarth and Honor Wheeler took the opportunity to photograph the glorious full moon, also known as The Hunter's Moon on the 9th October 2022 from various locations in North Kent and below are their superb results.

''Hunter's moon is mentioned in several sources as the Anglo-Saxon name for the Full Moon of October. This is the month when the game is fattened, and it is time to start preparing for the coming winter. Traditionally, this included hunting, slaughtering and preserving meats for use in the coming winter months.  Other names are Travel Moon and Dying Grass Moon. Some also called it Blood Moon or Sanguine Moon, which also refers to the hunting season. However, this name should not be confused with the term Blood Moon to describe a Total Lunar Eclipse.'' https://www.timeanddate.com/astronomy/moon/hunters.html

The latest ExoClock observations by Simon Dawes

Three more sets of observations of exoplanet transits for the ExoClock project by Simon Dawes. WASP-52b, Qatar-1b and HAT-P-6b.

WASP-52 b is a gas giant exoplanet that orbits a K-type star. Its mass is 0.46 Jupiters. Exoplanet WASP-52b orbits at a distance of 4.07 million km from its host star WASP-52, taking 1.75 days to go round its orbit. Its discovery in the constellation Pegasus was announced in 2012.

 

Qatar-1 b is a gas giant exoplanet that orbits a metal-rich K-dwarf star, which is one of the faintest around which a planet has been discovered by ground based surveys. Its mass is 1.294 Jupiters, takes 1.4 days to complete one orbit of its star and is 0.02332 AU from its star. Its discovery was announced in 2010.

  

HAT-P-6b was discovered on October 15, 2007.  It is located in the constellation Andromeda.  It takes 92 hours, 28 minutes, 17 seconds and 9 deciseconds to orbit its host star.  The planet HAT-P-6b is named Nachtwacht. The name was selected in the NameExoWorlds campaign by the Netherlands, during the 100th anniversary of the IAU, after Rembrandt's painting The Night Watch.  It is one of the few planets that is in a retrograde orbit around its host star.
