Hi all,

Comet Ikeya-Zhang is brightening a bit faster than predicted, and is already 
about magnitude 7.5, and should reach naked eye visibility by early March.

The preliminary elements given in my email of 5 Feb (from the IAU Circular) 
were not quite accurate, but are still probably close enough for locating the 
comet for the next few days. I will circulate new elements when the latest 
calculations are available.

In the meantime, here's a revised ephemeris covering the next week or so. 
Positions are given for both the old 1950 and the new 2000 co-ordinates. Mag 
= total integrated visual magnitude; D = comet's distance from Earth in AU's; 
R = comet's distance from Sun in AU's (1 AU = 93 million miles); Elong = 
angular elongation from the Sun in degrees.

February  2002.   Positions for 00:00 UT on the double date given.

There are also two  TV progs which may be of interest:

1. Tonight, Sunday, "Accidents in Space", BBC1, 23.40 - 00.30.  Accounts of 
the various USA & Russian fatal accidents in spacecraft. (Followed by the 
film "Trapped in Space" about a 'Shuttle' en route to Venus which gets 
damaged by an asteroid. No comment, as I don't know what it's like.)

2. Thursday 14, HORIZON, BBC1, 21.00 - 21.50: "Parallel Universes" About the 
new cosmology theories (TOE, etc).
