It's a good idea to set up a BAA Cometary Astrometry e-mail address. All my video astrometry is submitted directly to the MPC. I have a COBS username but I don't send them magnitude estimates; they don't want nuclear magnitudes from the central condensation.

During that interval I submitted 110 measurements of C/2017 T2, and a small number of C/2019 Y4, to the MPC. Nick - I'll collate my obs files and send you an attachment.

Cheers,

Alex.

Subject: [BAA Comets] Astrometry submissions to the MPC

I am just completing a short annual report on the Comet Section for publication in the next Journal but I don't have much visibility of the amount of astrometry done by BAA members since it is usually submitted directly to the MPC. Unfortunately, unlike magnitude estimates which I can download directly from COBS, there is no equivalent facility for astrometry.

If you are a BAA member and have submitted cometary astrometry to the MPC during the session (2019 August to 2020 July) could you please send me a short note directly to the email below with a summary of your observations. Alternatively, if it is easier, you can copy me your astrometry (in MPC 80 column format or ADES format) so I can do the analysis. Please send any astrometry as an attachment so that the formatting is maintained and not corrupted by your email client.

In the longer term I would like to set up an email address where BAA observers can copy any astrometry sent to the MPC. Any thoughts on that would be welcome.

Many thanks,

Nick James (ndj@nickdjames.com)
