ParticipantIndeed the phenomenon in Sue’s image is a Circumscribed Halo, nice capture but Stan’s image shows the Circumscribed halo as well but the white circle around the zenith is a Parhelic Circle. A full Parhelic circle is not a common phenomenon to witness in the UK usually only a portion is seen when a 22° Halo and Parhelia or Sundog are seen. The rarest, and I think the most spectacular halo to see in the UK, is a Horizontal Arc. Good luck seeing Horizontal arc in all the years I’ve been observing I’ve only ever seen a tiny portion of one. Atmospheric optics expert Les Cowley used to run a comprehensive atmospheric phenomenon website but alas only specific pages of it can be located during an online search.

ParticipantAs Simon and John have said this years Winchester weekend was excellent. Well done to those who put such hard work into making the weekend such a success. Great speakers, interesting topics and informative ideas, such a shame it didn’t last longer! Looking forward to 2023!

ParticipantFinally a comet that has remained, so far, intact (Sorry Nick 😉 Great to see a naked eye comet in the sky albeit just the core but it was worth staying awake for. Apart from the comet I also saw the ISS flypast of Venus, the Jupiter, Saturn & Moon conjunction, Mars and a rather pleasing Sunrise.
