CMHASD’s 60th Anniversary Dinner

The 30th November 2021 was Crayford Manor House Astronomical Society Dartford's 60th Anniversary however due to Covid the society was unable to celebrate at that time. Roll on to the 23rd April 2022 and we finally managed to have our 60th Anniversary celebratory dinner at The Boathouse, Danson Park, Bexleyheath. 

Member Diane Clarke wrote 'From the early evening of Saturday the 23rd of April 2022, a dinner was held at the Boathouse Danson Park to belatedly celebrate the Societies 60th anniversary.

Several members and their families came along but unfortunately our numbers were somewhat depleted due to some members and their families succumbing to summer colds and Covid.

But in spite of this we had a very enjoyable evening regaling each other with memories and tales of various Society lectures, social gatherings and outings, including our last summer barbeque. There was also talk about holding another barbeque later this year.

These photos give a flavour of the evening’s events that included a presentation from the Societies president Mr John Archer that included a look back at the Societies 50th Anniversary meal.

As can be seen John gave his speech to an appreciative audience.

Eventually we had to leave so everybody got together for the group photo, and with the evening’s festivities coming to a close we left in good spirits.

With several members deciding to continue the evening‘s festivities at another establishment.'

 

Below is a slideshow of photos taken by Diane Clarke & John Archer of the evening.

The society would like to thank Diane Clarke, John Archer and Malcolm Gough for organising the event and to Diane & John for sharing their photos.

Spotty Sun

More sunspots!!!!

Now up to AR2999 and counting as there is now a new very active region of sunspots appearing on the Sun as of today which have yet to be given an AR number. 

This new source of solar activity has so far been of C-class explosions which have in the past 24 hours hurled at least two CMEs into space. We (Earth) are not yet in the line of fire but as the active region rotates toward facing our planet things could change......

Simon Dawes captured these 2 white light image of the Sun on the 24th & 26th April 2022.

The Sun by Simon Dawes

Nice to see some sunspots on the Sun and there are quite a few visible at the moment as Simon Dawes shows in his recent images taken of the Sun on the 20th & 21st April 2022.  NEVER LOOK AT THE SUN DIRECTLY. Please click here for solar observing safely. 

Sunspot complex AR2993-94 is crackling away with M-class solar flares and did directly face Earth a day later. They are 'big' sunspots too.  The two dark cores are as large as Earth and a magnetic filament attached to one of the cores is more than 100,000 km long.

Sunspots are caused by magnetic disruptions of the visible photosphere of the sun which exposes the relatively cooler layers underneath - appearing as a black spot. 

The sun’s magnetic entanglements and disentanglement happen in 11-year cycles with each solar cycle having phases of low and high activity. Solar activity cycles have been numbered since 1775, when extensive recording of sunspot activity began.

We are currently in Solar Cycle 25, which has yet to reach its peak. The current cycle is expected to reach its maximum activity in late 2024 or early 2025, this means we may see more and bigger sunspots.

BAA Picture of the Week – Diane Clarke

Congratulations to member Diane Clarke for one of her images being selected for 'Picture of the Week' by the BAA (British Astronomical Association). 

The image that was chosen is called 'Eclipsed Moon Rising' and is a composite of 14 images taken between 8.17 - 8.26pm of the full Moon as it was rising above a distant horizon - see below.  There was a band of cloud that drifted across as Diane waited and as the Moon started to rise the cloud bank obscured parts of the moon as it climbed into the sky.  

Absolutely stunning.........

Pink Moon – 16th April 2022

On the night before Easter, the sky will look a little more "pink" due to the full Moon.

This is because the 1st full moon of the spring season is known as the Pink Moon and the name derives from a pink flower called phlox subulata that blooms in spring in North America.

While the moon itself won’t actually be pink, you might notice a slight change in its colour, depending on what time you viewed it on the 16th April 2022.

Members Jim Burchell, Diane Clarke and John Howarth all captured the full Moon last night on the 16th April 2022 as it rose, which appeared as a glorious 'pink' colour due to taking the photos whilst the Sun was still setting.

All photos were taken from locations in North Kent.
