A2 LINEAR - July 15, 2001 UT
Original ST6 30-second image taken at 9:03 July 15, 2001 UT.
FOV = 6.8 arc-minutes across. A tail is barely visible stretching to
lower right corner.
Using a histogram stretch reveals the full extent of the coma.
A galaxy, PGC 68502, magnitude 15.6(P) appears on left.
Here a posterizing filter is applied to the image to model the
shape of the brightness variations.
Further image processing reveals the T-shape first observed (I believe)
Masi from Italy a few days prior to this shot.
A detail of the nucleus shows no sign of fragmentation. Each pixel
is about 1 arc-second across.
