Solar Observing at Hall Place & Gardens – Sunday 6th August 2023

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

Sunday 6th August 2023 – What a glorious day to be out solar observing which is what Crayford Manor House Astronomical Society Dartford (CMHASD) where doing at Hall Place & Gardens 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.

Chairman John Archer wrote ''On Sunday 6th August, the team from CMHASD set ourselves up for the first of our two Solar Observing events at Hall Place & Gardens.

The forecast was for early morning sun, followed by sunny intervals until around 11am, but cloudy conditions until the arrival of rain at 4pm. Given that our timeslot was effectively 11am – 3pm, we were nervous to say the least!

Our pitch was on the grass at the end of the path from the main entrance to the gardens, and we were quite close to the hard standing outside the art gallery and café. With the date being chosen to coincide with the Farmers’ Market, we experienced good foot-fall and our flag was prominent for visitors as they arrived.

At one point we had around a dozen members in attendance and the public were treated to displays of sunspots the like of which we haven’t seen for years. Whilst the big Dob Anita was an immediate attraction, we had Tinie, two solar projectors and a range of H-Alpha and white light filtered scopes with which to demonstrate safe solar observing to a very interested public.

Of particular note was the filtered refractor which Honor had set up with a digital camera attached, affording visitors a proper “live view” of the surface of the sun. Each of the scopes were able to display clear views of sunspots such was their size and quantity. This solar cycle has certainly picked up in terms of activity and although the local forecast was for cloudy conditions, we very much lucked out in terms of clear spells so the public were very fortunate that during the period while the Farmers’ Market was trading, we were able to keep them entertained and educated.

The Crayford team returns again later in August for our second session but there’s no doubt this first visit to Hall Place for Solar Observing in 2023 was a great success.''

Below is an image of the Sun on the 6th August 2023 taken by member Honor Wheeler.  The Sun was very active with lots of sunspots. Image acquired using an ED80 Refractor, EQ3 Synscan mount, Canon M6 MarkII, 2x lens Barlow and ISO200/ exp 1/1250s.

CMHASD will be back at Hall Place on Saturday 19th August 2023 to do some more Solar Observing with the public. Please do come and join us!

Thank you to John Archer, Diane Clarke and Honor Wheeler for sharing your photos of the day with us.

Informal Nights at the Society

A few photos showing what members get up to on our 'informal nights' at the Society.  Activities range from observing, testing/setting up members' latest equipment purchased, fixing members' equipment, presentations, general chit chat & banter plus games.

Noctilucent Cloud (NLC) – 5th July 2023

Noctilucent clouds put in a rare appearance on the 5th July 2023 from around 10.50pmish until 11.30pm and a few lucky CMHASD members got to see them :-)

Below are the photos that members Jim Burchell, Diane Clarke, Martin Crow and Sonia took of the clouds.

Jim's NLC images, taken with a Pentax KP.

Diane's NLC image, taken using a Canon M50 Mk2, lens Canon 100mm macro, f3.2 @ 2.5sec, ISO 400.

Comet C/2023 E1 (ATLAS) by Dr. Mike Rushton

A rather splendid image of Comet C/2023 E1 (ATLAS) taken by CMHASD trustee and secretary Dr. Mike Rushton on the 12/13th July 2023 in Ursa Minor. 

Mike wrote ''This is C/2023 E1 (ATLAS) last night.  Approx Mag 14.5 with a greenish coma. The bright star in the image is Mag 7 and the limiting Mag 17.5.  Perihelion was 1/7/23 and closest to earth will be on 18/8/23. This was a 20 min exposure with my eVscope.'' Imaging started just before midnight on 12/7/23 (23:57 BST).

Comet C/2023 E1 (ATLAS) was spotted on the 1st March 2023 by the NASA funded Asteroid Terrestrial-impact Last Alert System (ATLAS). At the time, the comet was a +19th magnitude object moving through the constellation of Virgo.  

On July 1 this Comet ATLAS reached perihelion, its closest approach to the Sun.

To date the comet has now moved into Draco and will move into Cepheus towards its closest approach to Earth mid-August.  On August 18 this visitor to the inner Solar System will only be 3 light-minutes or so from our planet.

Based on its inclination to the ecliptic plane (38 degree) and orbital period of about 85 years C/2023 E1 (ATLAS) is considered a Halley-type comet.  Though the comet currently has a 'C' designation for a long period comet versus periodic comet; that will probably change as 85 years is much less than the 200 year orbital period cut off defining the 2 categories of comet.

Below is the report from SETI/UNISTELLAR Mike received back after submitting his imaging data.

Mike said ''I have had the photometry back and it was brighter than I thought at Mag 12.8. See the report from seti below. The little image in that report is stacked on the moving comet. The original image I sent was stacked on the stars.''
