Comet C/2023 A3 (Tsuchinshan-ATLAS) is a long-period comet from the Oort cloud that was discovered in 2023 by the Purple Mountain Observatory in China in January 2023 and independently by the ATLAS (Asteroid Terrestrial-impact Last Alert System) in South Africa in February 2023. It was named after both observatories.

Four members of CMHASD; John Archer, Gary Hunt, Jo Southgate and Honor Wheeler met up at Top Dartford Road at around 18:30 to see if they could spot comet C2023 A3 Tsuchinshan - ATLAS on the 12th Oct 2024.  The rain cleared just in time and the sky was clearing of cloud as they set up. It took about 25 minutes looking but in the end they spotted the comet nucleus with a pair of 8x42 binoculars in the orange glow of the sunset i.e. in the Western sky approx 10 to 20° above the horizon :-)

Below are some fantastic images of the comet taken by Honor.  These images were also the 1st ones of the comet to be put on the British Astronomical Association (BAA) website - well done Honor!

A great image capturing Comet C/2023 A3 (Tsuchinshan–ATLAS) by member Jim Burchell from Swanley. 
Jim said ''I took this image on the evening of 15th of May when the Comet was in the constellation of Virgo with my Seestar S50. As you see the Comet is showing a small tail....''

We had an informal meeting over Christmas where Martin took the members through using AstroImageJ (AIJ) he covered the following...

  • Loading an image
  • analysing stars in an image
  • plate solving an image
  • batch processing images to calibrate them
  •  aligning and stacking images
  • photometry on a sequence of images

We will be attempting to observe Comet PanSTARRS C/2011 L4 on the 12th March 2013 at the Pavilion. The comet will be 11 degrees above the horizon at 19:00, close to Uranus; the Sun - according to StaryNight pro 4.5 sets at 19:00 so we will want to set up any equipment before sunset.

This will be a challenging observation, the comet is predicted to be close to its brightest but it will be in bright twilight
CAUTION SUN MUST HAVE SET BEFORE YOU USE YOUR BINOCULARS
