Your pic appears to be at odds with Pete Lawerence

His was for the 16th too.

I don't mean to be unnecessarily critical, but the image at this
location shows a very large bright naked eye comet with a tail some 20
degrees long. I hate for people to be disappointed. This comet (and
its other bright component, which isn't depicted at all) are truly
wonderful, even if they aren't huge and bright.

For those who may not know, currently 73P has two fragments (C and B)
that are just barely visible to the unaided eye and show tails between
30' and 2 degrees in length (depending on the instrument, darkness of
sky, and whether or not the comet is acting up that night). The B
component is currently about 10 degrees to the north of the "primary" or
C component. They are both nice little binocular objects and they make
grand sights in the telescope.

Soon the moon is going to be out of the way for northern-latitude
observers and we should get one last look in a dark sky before they move on.

Clear skies,
Greg

I went out this 4 am to see if I could spot it, no such luck, 1st, a layer
of high thin clouds where moving past, 2 the moonlight wiped out most
everything, 3rd the light dome from Palmdale/Langcaster/Dimond Jims didn't
help. I sat down with my 10 x 50's and for 15 mins scaned that area of the
sky, but I didn't find anything and I used the S&T map too.

I said that off the top of my head, but now that I've checked it's not
quite right. The motion of the comets offsets the moon for the next few
days. Eventually, most latitudes will get a last look in darkness but
it won't be until next week, starting around the 22nd. Equatorial
latitudes are favored with the longest and best view in darkness. At
40N the comets will be visible low in the sky at the onset of morning
twilight from the 23rd trough the end of the month. By then they will
have faded significantly.

components are are suitable for printing see:

I realize this and hope that people recognize that the comet image shown at
this CDC page is only for location marking purposes and is the default
comet image for the program. Even the faintest of comets depict themselves
this way on the program and that is one reason I have thrown the visual
magnitude up with the image.

I acknowledge the superiority of your own program to this freeware, but the
freeware is all I have and additionally it gives permission to use its
images at will and where needed.

I wasn't trying to one-up you. Like I said, I'm concerned that the
depiction is going to mislead people. If there is a disclaimer about
the size of the comet, I didn't see it. Sorry.

As for "permission to use images at will where needed", for the record,
users of my software have the same permission.

Clear skies,
Greg

Good point, Greg. I shall add it now to the image caption info.

Totally USELESS information about tracking the position of the comet!
