Subject: last chance for Mir !!
Two fine opportunities to see the Mir Space Station are Monday and
Tuesday morning before dawn. Possibly, the last two. Possibly, weather
will mean there are none left. Both the meteorological and orbital
calculations are pretty uncertain beyond a few days, so it is hard to
tell. There may be a good pass on the evening of March 11, if Mir is
then still in orbit.
On Monday morning, Mir will exit the shadow of Earth about 6:12 am, (I'm
not fudging this, so be early!), about 13 degrees up at azimuth 320,
moving up to the right. She will arc over Polaris, the North Star,
culminate 127 seconds later at 51 degrees over 35, and then pass midway
between Vega and Deneb, the 2 northernmost stars of the Summer Triangle,
then pass very near Altair, its Southern star. Brightness is hard to
predict, anything from mag 0 to -4 would be unsurprising.
A group led by space pioneer Bob Citron is planning to observe the
reentry next month from a jetliner about 3 Mm (= 3000 km) South of
Tahiti: http://www.mirreentry.com
Cheers.

Higher ALtitudes are better.
The shuttle will be moving left to right, and this may require
recalculation due to maneuver(s); if you plan to observe and need my
assistance with that, please contact me.
