Full Moon Rising – 11th August 2022
Three CMHASD members imaged the full moon - the 4th and last supermoon of the year rising on the 11th August 2022 and below are their stunning photos.
A full moon occurs when the moon and sun are opposite each other and sunlight strikes the moon face-on.
The August full moon is also known as the Sturgeon Moon so this was a Sturgeon supermoon!
Nasa explain: 'The term 'supermoon' was coined in 1979 and is often used to describe what astronomers would call a perigean (pear-ih-jee-un) full moon: a full moon occurring near or at the time when the Moon is at the closest point in its orbit around Earth. Therefore the moon appears larger and brighter than usual as it reaches the full moon stop of its cycle. A supermoon will usually cast around 30 per cent more light onto Earth than it does when it is at its dimmest. This is because the supermoon will be closer to the sun's rays and therefore able to reflect more light.'
We have already witnessed three supermoons this year, in May, June and July. Surprisingly, supermoon streaks like the one we have seen this year are not uncommon. 2023 will also see four consecutive full supermoons, as will 2024. Even 2025 has three in a row.
Member Diane Clarke wrote 'Fellow member Honor Wheeler sent out a message reminding us that the full moon would be rising, so along with fellow member Jim Burchell, Honor & myself went to a local vantage point to await moonrise above the distant horizon. Unfortunately we were a little late in arriving and from the remaining colour in the sky we no doubt missed a superb sunset. The image below shows moonrise over a 15 minute period as it breached the horizon and proceeded to climb into the late evening sky. The middle image was taken 8 minutes after the initial breach and the image at the top of the frame was taken 7 minutes later as the evening was moving into night. Shortly after we all decided to depart after experiencing another spectacular moonrise.'
Diane's image was acquired using EOS M50m2, Sigma 18-250mm @ 250mm, 1/6 - 1/15 sec f/6.3 and ISO 1600 at 8.57pm to 9.12pm.
Jim Burchell's full moon rising images below were all taken with a Pentax KP at 300mm, F7.1, 1/3s & iso 200.

CMHASD Solar Observing at Hall Place & Gardens – Saturday 20th Aug 2022
NEVER LOOK AT THE SUN DIRECTLY. Please click here for solar observing safely.
On Saturday the 20th of August several members of the Society were present for the second of our 2 solar observing sessions at Hall Place & Gardens. The event took place on the patio with a small farmers market close to the gallery so there was a constant stream of people wanting to look, some just wondering what was going on and and others who clearly had an untapped interest in astronomy. Hopefully we will see some of those people in the future.
At our previous session at Hall Place on Sunday the 7th of August we and those who came to see us were treated to 4 hours of sunshine unfortunately on this occasion we were not so lucky with varying amounts of cloud being present throughout the session. When the clouds did clear and the sun became visible we were able to offer safe views of the sun to the public through the telescopes. When we did get glimpses of the Sun - the public were thrilled with what they saw; even if it was often in 20 second bursts!!!
Overall we had 7 telescopes on hand including 'Anita' one of the clubs Dobsonian telescopes and during clear spots every telescope was in use. We also had a couple of tables of displays including details of Sun spots, a solar projector and other interesting Astronomy facts which proved popular too with the public.
Whilst the weather was disappointing the day was a great success and the Society would like to thank all those members who helped on the day.
Below is a slideshow of photos taken of the day by members John Archer, Simon Dawes, Diane Clarke and Dr. Mike Rushton - Thank you for sharing them with us. Also thank you to Diane Clarke & Simon Dawes for your help writing this post.

Prior to going to the event member Simon Dawes took the opportunity to image the lone sunspot on the surface of the Sun at home and this is his image. This was the sunspot that the public would have seen through the telescopes during clear gaps in the cloud.
Astronomy Apps & Software document
A word document that you can download detailing some useful astronomy apps and software has been uploaded to the New to Astronomy page. Thank you to member George Buckberry for compiling the list.
Solar Observing at Hall Place, Bexley – Sun 7th Aug 2022
Sunday 7th August 2022 - What a glorious sunny day to be out Solar Observing which is what Crayford Manor House Astronomical Society Dartford (CMHASD) where doing at Hall Place in Bexley. What a busy day it was too! Several telescopes were set up to observe the Sun safely and members of the public were invited to do some solar observing which was readily accepted by many. The Sun put on a good display having several sunspots and prominences for the public to view.
CMHASD will be back at Hall Place on Saturday 20th August 2022 to do some more Solar Observing with the public. Please do come and join us!

Crayford Manor House Astronomical Society Dartford awarded National Archives; Archives Revealed Scoping Grant
Some very good news announced yesterday 21st July 2022 - The National Archives; Archives Revealed Scoping Grant has been awarded to CMHASD to assess the value and future of our Hewitt Camera Archive Collection!
See the National Archives Press Release: https://www.nationalarchives.gov.uk/archives-sector/finding-funding/archives-revealed/scoping-grants/current-projects/
Crayford Manor House Astronomical Society Dartford (CMHASD) are the authorised custodians of the Hewitt Camera Archive Collection, containing over 11,000 wide-field sky glass/plastic satellite and astronomical photographic plates. This unique collection covers a historic period of 30 years from 1965 and relates to both the Northern and Southern hemispheres (the UK and Australia).
This Archives Revealed scoping grant is the first stage for funding the restoration, conservation, safeguarding, cataloguing, digitisation, and public sharing of this unique collection before deterioration and loss occurs. The Hewitt Camera Archive Collection is an insightful, historical and scientific resource into the UK’s part in the early days of space exploration. CMHASD is committed to sharing this valuable astronomical research archive with current and future generations as a physical and digital resource for all.
Quote from CMHASD President John Archer: "CMHASD is thrilled and grateful to The National Archives, The Pilgrim Trust, and the Wolfson Foundation for the award of this Archives Revealed scoping grant for our Hewitt Camera Archive Collection. This grant will enable our small charitable society to fund expert opinion and guidance to assess the digitisation, cataloguing, and planning towards making this unique UK space history and astronomical photographic collection safe and publicly available to the world. So…watch this space!”
The Society would like to thank Gary Hunt and team for your efforts securing the scoping grant. Fantastic news & well done!
Gary wrote 'This is exciting news but this is only the first step on what may be a long journey? Further substantial funding will be required to undertake the completion our objectives derived from the outcomes of the forthcoming Archives Revealed scoping report. The scoping report will determine the value (in terms of scientific, cultural and historical context) of the CMHASD Hewitt Camera Archive Collection and will also make recommendations on how to maximise exploitation and preservation of the collection.

We are always grateful for offers of help or ideas for achieving our objective of fulfilling our solemn commitment to keeping the Hewitt Camera Archive Collection safe and allowing full exploitation by the astronomical, scientific, historical community… and lets not forget yourself!'
Dartford’s Big Day Out – July 2022
On the 16th July 2022 Crayford Manor House Astronomical Society Dartford (CMHASD) exhibited at Dartford’s Big Day Out in Central Park, Dartford.
It was an extremely busy & interesting day. Several members of the public took the opportunity to drop by for a chat, observe the current activity on the surface of our nearest star the Sun using the 3 telescopes that were on display and to view our various display boards showcasing the societies activities. Our 3D photographs & the planet game also proved to be very popular too!
Safe views of the Sun were offered by various CMHASD members that helped throughout the day using 'Anita' one of the societies Dobsonian telescopes built by members Steve Floodgate and David Grist (see Building Dobsonians) whilst member Jim Burchell offered safe views through his refractor. Both of these telescopes were showing white light views of the sunspots currently visible on the Sun’s surface.
Member Diane Clarke offered safe views of the sunspots on the Sun too as well as the Sun’s various prominences and surface detail with her Ha (Hydrogen alpha) line telescope, see the 2 photos below.
Both images captured an absolutely massive prominence on the Sun at the 11 O'Clock position; this wall of plasma was more than five times taller than our entire planet Earth! There were also prominences captured at the 1,2,6 and 10 O'Clock positions too in the images.

Beautiful Noctilucent Cloud (NLC) spotted early morning on the 15th July 2022
OK so it is the NLC season but WOW another sighting of these rare clouds by members. A very bright & beautiful display it was too that lasted again for quite a while into dawn until 4.15am.
An alert went out at 2.33am from member Sonia as she had spotted them very low down in the North East. Two members; Diane Clarke and Jim Burchell picked up the alert and so joined Sonia in photographing the beautiful display that was to follow. All photos where taken from various locations in North Kent by the members.
Below are 4 images by Jim Burchell taken at around 3:30 am. All image's were taken with a Pentax K70 and there has been no processing.
Below are 2 images taken by member Diane Clarke.
Panoramic view of the NLC. Diane wrote ''It went on to develop enabling me to capture 6 separate images taken at 03.30hrs that I used to create this panorama encompassing the splendour of this NLC.''
NLC at 4am as it began to fade in the North West.
Below are some images taken by Sonia using an iPhone. Also seen & photographed that morning were the planets Mars, Jupiter and Saturn, the Moon and a very curious fox who kept watch on Sonia whilst she took her photos.
NLC and the star Capella at 2.41am.
NLC developing nicely at 3.03am.
NLC at 3.10am - more finer detail emerging.
NLC at 3.21am.
NLC at 3.22am. You can see how bright they were next to a street light.
NLC at 3.38am. The NLC moved from the North East to the North West as dawn approached.
The Sun – 15th July 2022
More super images of the Sun by member Simon Dawes taken on the 15th July 2022 showing the Sun speckled with sunspots. Details of how Simon took the images are on the pictures.
