Comet Image Naming Convention

Observing Sections receive many images, which are often given names such as DSCN001.jpg or comet.png. Such names are not very informative! In order to make archiving and cataloguing of comet image files easier, please use the standard naming convention, which is [comet]_[yyyy][mm][dd][l]_[hh][mm]_[observer].[img], where:
[comet] is the comet identifier eg 2006p1,
[yyyy][mm][dd] is the date eg 20070110,
[hh][mm] is the time eg 1703, and is optional
[l] is the image number taken by the observer on that date eg a,
[observer] is the observer's surname or initials eg shanklin,
[img] is the image format eg jpg

2006p1_20070108_mpm.jpg is the first jpeg image that Martin Mobberley took of 2006p1 on January 8.
4p_20061218_2141_ds.jpg is an image of 4P/Faye by David Strange on December 18 at 21:41.

Any further information about the image must be included in the image. This should include the comet name, the date and time, location, the camera, lens focal length, exposure, film speed etc.

J D Shanklin, Nikon D70 200mm f6.3, 1/5s at ISO1250

For CCD images, please also include the orientation (with arrows indicating north and east) and the image scale, usually be giving the frame dimensions. Example image of 29P/Schwassmann-Wachmann from Rolando Ligustri on 2006 December 24 with image name 29p_20061224_ligustri.jpg.

Submissions frequently depart from the convention, so please do not use the following incorrect forms:
C2006P1 or McNaught for [comet]
10012007, 10Jan2007 or 2007Jan10 for [yyyy][mm][dd]
