Mars 6-7 Aug at Mill Hill
Long observing session at University of London Observatory, London NW7, last
night, using 8-inch Fry refractor (1862-vintage Cooke). Mars had its "less interesting" side turned towards Earth but at times we had fairly good seeing despite warm temperatures and high humidity. Took some video footage through filters for combining frames later, and CCD colour images. We will mount these on our web site ASAP. Seeing was best from about 2-3.30am BST. We could see a small bright dot on the limb near the N polar regions of Mars (pole cap peeking over the horizon?) and the S polar cap has shrunk considerably in the past few weeks. Also, it appeared to us, around 3am BST, that there were hazy clouds along much of the morning (east in the sky) limb.

Mike Dworetsky, Francisco Diego There are now a few images in the "News" section of the Observatory web site, but would you believe it, the whole site is temporarily down, a malfunction that needs sorting out tomorrow after our IT expert gets back from a mandatory course in first aid. :-) http://www.ulo.ucl.ac.uk -- Mike Dworetsky (Remove "pants" spamblock to send e-mail) |

Mike Dworetsky, Francisco Diego At the risk of seeming to talk only to myself, there is now another image of Mars from the video we took--a coadd of about 200 selected frames (unfiltered) showing Mars at 0107 UT on 8th August. We have used an albedo map to put names to features. Last night (11-12 Aug) the seeing was very poor so no observing was possible. -- Mike Dworetsky (Remove "pants" spamblock to send e-mail) |

Where are they? http://www.ulo.ucl.ac.uk/images/mars2003/index.html Accessible by link on the home page, beneath pic of the Radcliffe telescope. What has happened is that they haven't also been linked via the news link. I'll get that fixed later today. -- Mike Dworetsky (Remove "pants" spamblock to send e-mail) |
