Last week I was at the Royal Society in London for the first day of a
series of meetings about Comet 67P. The Rosetta mission is now entering
its final stages with end-of-mission planned for late September when the
spacecraft will spiral in to "land" on the nucleus. 67P is now getting
quite faint and it is low in the western evening sky from the UK and
difficult to image due to the summer twilight.
While I was there I met Padma Yanamandra-Fisher who reminded me that ESA
have set up their Planetary Science Archive to receive amateur images of
the comet. This is the first time that they have done this and a great
opportunity for us to share our raw data with the pros.
In order to upload data you need to be registered. If you are not
already registered you can request access using this page:

There are some fairly simple rules for uploading data. The images must
be in FITS format and the files must be named in a particular way.
Details of this are in the Observing Guide here:
http://rosetta.jpl.nasa.gov/amateur-observers-guide
In this guide the filename format is defined as:
YYYYMMDD_HHMMSS_67P_FSSNNvx.FIT
where F = filter, SS = exposure time (in s), NN are the observer's
initials, vx = version of file (v1, v2 etc). Wendy Clark has produced a
useful guide describing how iTelescope images can be renamed and
uploaded using a particular FTP client. This guide is available via the
Facebook 67P group but the renaming is fairly straightforward since all
the information needed should be in the FITS header.

If you can't access this drop me an email and I'll send you a copy.
Let me know if you submit any images or have any questions.
