It is currently well-placed for observation in Sextans. The following total magnitudes are from IAUC 6320 and are visual unless otherwise noted: Jan. 4.83 UT, 13.8 (Kojima, Chiyoda, Japan, 0.25-m reflector + CCD); 21.34, 13.2 (A. Hale, Cloudcroft, NM, 0.41-m reflector); Feb. 2.64, 14.2 (Kojima); 13.25, 12.6 (R. Keen, Mt. Thorodin, CO, 0.32-m reflector; 2'.5 coma); 15.66, 13.3 (Kojima); 18.06, 13.8 (J. Carvajal, Teruel, Spain, 0.44-m reflector); 19.54, 11.6 (Kojima; strong, nearly stellar condensation with a faint coma extended toward the northwest); 20.27, 11.8 (Hale; 0'.2 coma). IAUC 6320 MIR SPACE STATION February 21, 22 and 23 provide a good opportunity to observe the Russian space station Mir. It should be visible from the UK/Ireland and much of Europe as it is chased by new crew on a Soyuz (due for launch noon Feb. 21 and taking 2-3 days to dock). Mir can flare up to mag -6 when sunlight catches solar panels and it is usually mag -2 when overhead. Soyuz could be mag +2 according to David Moore of Astronomy Ireland. Those with Web access can get predictions of the precise time to watch each evening from various sources (start at Astronomy Ireland's home page http://www.iol.ie/~ai and follow the links from there for example). David Moore would be interested to receive sightings quoting postion (nearest town, or lat/long), UT time and date, time difference between Mir passing a star and Soyuz passing the same star (or angular separation if say closer than 10 degrees). His e-mail address is ai@iol.ie. Mir reaches its maximum altitude at the following times for London, UK: 21/2/96 19:14 20:50 22/2/96 18:19 19:55 21:31 23/2/96 19:00 20:36 Nick James.
