Comet Linear (WM1) Brightens. Comet LINEAR WM1 is being
watched with particular interest by astronomers because its
ion tail might yield clues to understanding the solar wind
expelled from near the Sun's poles. Photo Credit: Arturo

Comet
LINEAR was first seen late last year — hence its name when
it was out past Jupiter and still very faint. In the above picture
from the Curtis
Schmidt 0.6-meter Telescope in Chile, a 30-second exposure in
red on December 4 captured detail in Comet LINEAR
WM1's emerging dust tail. The
W stands for the second last week of the year and the 1 means the
first comet found in that time.
A
comet bright enough to be seen with binoculars is swooping into
southern skies. Comet C/2000 WM1 (LINEAR) continues to brighten
and develop tails as it nears its closest approach of the Sun in
late January 2002. Optimistic sky watchers hope that Comet LINEAR
WM1 will undergo an even greater (and unexpected) brightening to
the point where its coma and tails are easily discernable to the
unaided eye.
It
is magnitude 5.8 in brightness — too faint for naked eye viewing
in towns or cities. From now on you'll need dark skies (away from
lights) and either a telescope or binoculars. The tail will
increase in size throughout the month of December as it travels
closer to the Sun, however it is moving away from the Earth during
this time. Therefore the magnitude will remain steady at 5.7 until
the new year.
Comet
C/2000 WM1 (LINEAR)'s closest approach to Earth was on 02 December
2001 with distance 0.316
AU. The
diagram below shows where to look out for comet LINEAR from
Brunei. The dates shown display the position of the comet on the
given date at 19:30 Local Time. Note that the path of the comet is
moving southwest direction.
