tails towards the sun. So I think there is no possibility to see the
anti tail now and in December.
But the software is not a professional software to simulate the
comtary tails. Akimasa Nakamura commented me that simulation using a
professional software, for example synchron analysis, is required.

Mike Halloway has just posted in the mailing-list [Comet-images] a
shot of C/2003 T4 (LINEAR). Once correctly oriented, a well defined
structure (tail, trail, or whatever) extending almost 3' toward N-NW
is visible. No details are given for the instrumentation and the time
of the exposure, however the Guide 8 software I'm using suggests a UT
close to 00h 30m on December 2, 2004. It's interesting to notice some
kind of assimetry in the shape of this feature: the W side terminates
much sharply than the E side. The original image is available at:
