Martin -------- Forwarded Message -------- Subject: Comet 21P Date: Thu, 13 Sep 2018 19:00:13 +0000 (UTC) From: Paul Abel To: Guy Hurst , Martin Mobberley , Chris Go , Tom Kerss , Sean Walker , ALPO Japan Toshihiko-Ikemura , Nick James , Doug Daniels , Mark Kidger , Damian Peach , Pete Lawrence , Bill Leatherbarrow , Richard MCKIM , Ian Sharp , Kevin McNulty , Bill Sheehan , Jeremy Shears , Mark Parrish , Alan Friedman , Brian Colville , Timothy J (3223) Parker , Cristian Fattinnanzi , Nick James Hi all, I waited up for 21P/Giacobini-Zinner last night- by 0154UT it was at a reasonable height above the observatory. I made two drawings, one at x25 and another at x111. There was a little mist present and transparency was probably less than average, as a result the comet appeared to have a low surface brightness. At x25 the nucleus was visible and the tail was just detectable. At x111 more structure was visible in the tail and nucleus. Recent images show the comet has a greenish tint but I was unable to detect this, visually it appeared a bluish white colour. Best wishes, -Paul ----- Dr. Paul G.
