Explanation:
Arcing toward southern skies in late March,
this faint comet LINEAR
-
the one officially
designated C/2001 A2 (LINEAR) -
brightened unexpectedly.
The outburst, apparently due to
the fragmentation of its nucleus,
delighted observers as the comet eventually increased to
naked-eye
brightness.
Comet
LINEAR's tail also grew and in
this mosaic of images from
May 18, astronomer Gordon Garradd has carefully followed the fluorescing
filaments of LINEAR's gas tail stretching 1.5 degrees (the width of
three full moons) along the anti-sunward
direction.
The inset close-up near the top clearly shows two bright condensations
in the
cometary
coma, indicating the presence of a split nucleus.
This comet LINEAR
made its closest approach to the Sun on May 24.
Still showing
off for southern skygazers at about 5th magnitude, it
will become more easily visible for northern observers by late June.
