From: TerryMosel@aol.com Date: Sat, 28 Dec 2002 09:55:39 EST Subject: Comet & Party Hi all, Here are the latest elements for Comet C / 2002 X% Kudo-Fujikawa, courtesy of Prof Mark Bailey. T = 2003 Jan 29 .0027 Eccentricity (e) = 1.0 q = 0.190040 omega (peri) = 187.5663 OMEGA ((Node) = 119.0697 Inclination (i) = 94.1530 It is currently predicted to be almost 6th magnitude, and could attain visibility with the unaided eye in the first half of January. It then brightens further, predicted to reach 2nd magnitude in the third week of January, but will then be getting very close to the Sun. It is still just circumpolar, particularly for observers in the North, but is gradually moving south-eastwards, through Hercules. You can just find it low in the NW sky as soon as it gets dark; it then passes just above the N horizon under the Pole at Lower Culmination, and rises again getting reasonably high in the NE sky just before dawn. If you don't have a skycharting programme with the facility to insert new elements, here are some positions for the next week or so, at 0h on each date: RA (2000.0) Dec Dec 28: 17h 39.93m +33d 44.5' Dec 30: 17h 54.78m +31d 04.1' Jan 01: 18h 09.05m +28d 30.3' Jan 03: 18h 22.70m +25d 48.9' Jan 05: 18h 35.74m +23d 00.9' Jan 07: 18h 48.15m +20d 07.4' IAA XMAS /NEW YEAR PARTY: Don't forget to book your ticket(s) for the social event of the year, on Saturday 4 January, 7.30 p.m., at the Tudor Private Cinema, Comber. The film is 'Space Cowboys', and a great selection of buffet food & drinks are included in the price. Full details were sent out with STARDUST: if you've lost them, or didn't get them, contact me immediately by return, or John Hall, tel 9084 3109, or email at < jimmyaquarius@btinternet.com>. Great fun, and great value, with various family tickets available. You can also try to spot Mercury low in the SSW sky for the next few evenings: if you have never seen it in the month of December, now's a good chance to try to do so. Look from about 16.50 to 17.30. This evening (and for the next 2 evenings or so) you can locate it by taking the mid-point of the line between Vega and Deneb and continuing it down through Altair almost to the horizon. It will appear as a faint pinkish 'star' in the twilight: binoculars will help you to locate it first. But don't look until AFTER the Sun has set! Happy New Year to you all... Terry Moseley
