I wouldn't normally post an announcement about when and where to look for
the Hubble Telescope during its Southern California passes, since it's not
as bright as the space station or shuttle, and therefore a challenge to see.
But Hubble is in the news right now because it has a command and data
computer glitch. A repair mission to the 18-year old telescope has been
delayed until early 2009 to assess this new problem.
The Hubble Telescope is visible in our skies tonight! I plan to give it a
try from light polluted Monrovia.
Sunset is at 6:11 p.m. At 6:45 p.m. Hubble rises above the WSW horizon, and
reaches 10 degrees above the horizon at 6:48 p.m. Between 6:48 and 6:55
Hubble will slowly pass just above Venus, and then above Jupiter, and will
disappear from our view when it enters the Earth's shadow in the ESE at 6:55
p.m.It will look like a faint slowly moving "star, much fainter than the
larger the Space Station.
The brightness magnitude is 2.7, which is near the brightness of the stars
you'll see near Jupiter - the stars of Sagittarius. Venus and Jupiter are
much much brighter.
There are other good passes this week. You can find them, and customize
