This looks like one end of a dust particle trail which drifted to/from 714,1017 during the ~19 second frame exposure time.

Image 15:54 733,990 is somewhat promising, but I see no other
comet-like images connected to it.

which probably means nothing.

But in Lasco C2, the PAIR of comets appear to enter the frame from the left, just about at the level of the corona circle. The pair can be seen moving from left to right toward the sun beginning at 2003/11/06 00:06 and continuing past 2003/11/06 09:06

Subject: ESA fellowship candidate Date: Wed, 24 Sep 2003 15:07:50 +0200
From: Philippe Lamy To: xxx@xxx, Lamy Philippe

Dear Luigi,
As you probably know, the LASCO coronagraphs aboard SOHO has
detected and are still detecting hundreds of sun-grazing
comets and has also observed several bright comets. So far the tasks of
detecting and analyzing the sungrazers were carried out by the
US side (NRL) of the LASCO consortium (essentially Doug
Biesecker) with important assistance from us. Because of
heavy involvements on other space programs, NRL has
discontinued these activities.

I am strongly encouraged by several colleagues and by the
ESA SOHO project scientist Bernhard Fleck to take over
those activities in Marseille. Following extensive discussions,
our preferred approach is to take advantage of the ESA
External Fellowship program to secure the funding for a
postdoc to work here. The application will obviously be
strongly supported by the SOHO project scientist.

I am therefore looking for a postdoc from an ESA member
state (excluding France but including Canada) having the
appropriate background (solar system studies, preferably
comets + image analysis, preferably with IDL) interested
in this program. It is anticipated that 50% of his/her
time will be devoted to the handling of LASCO comets
(astrometry + photometry) and the other 50%, to related
scientific analysis (for instance, origin of the sungrazers,
modeling of a sublimating nucleus near the Sun, analysis of
the dust tails, physical properties of cometary nuclei,...).

Please disseminate this information among your young colleagues
or directly inform me of any potential candidate you may know.
The fellowship is nominally for one year but is always extended
to two. > More info is available at: >
http://www.esa.int/hr/educational/fellow.htm The next round of
selection has a deadline of 30 September, still leaving enough
time to prepare the application form (essentially a research
program). Otherwise, the next deadline will be 31 March 2004.
Thanks for your help and kind regards,
Philippe

Just somthing I don't understand, in the C3 photo dated 2003/11/05

00:18 there are four objects that may be digital interference but
I have never seen that shape in a C3 photo.
The "shapes are the same size and shape, positioned horazontally and vertically in random spots within the photo.
The easy item to spot is just below and to the left of the disk but there are two much lower and to the right near the bottom and the last is very near the top and just slightly to the right.
Perhaps you can identify?

Regarding your post Nov 15 2003 22:26:51, this does
not appear to be a comet
I believe your positions:
0042 819 899
0142 804 893
are both faint (~9.5 mag) stars.

Regarding Nov 23 2003 10:34:09 & 10:44:56: the posted positions
cannot be a comet. The object turns right and accelerates on
your third reported position. This is not a possible orbit.

Congratulations on the Nov 22 2003 14:19:10 comet, which I see for 7 or 8 images.

From C3 1/2 Res Animated GIF Approx 2003/11/26 1042 

Through 2003/11/26 2342.

Faint object transits from mid bottom just right
of center moving upwards and to the left in
what looks like a slightly eliptical orbit.

I can't pick it out in the individual graphics, but it
is clearly discernable in the fast action segment of
the current gif.
