[BAA Comets] C/2018 A1 (PANSTARRS)

[Peter Carson]

Hi Nick,
I obtained astrometry of C/2018A1 on the 19th. I also measured C/2018A3 and 
it was either A1 or A3 that was some way from the predicted path, I can't 
remember, but not by the amount you suggest.
I've attached the astrometry and images for your info.
Peter

Morning all,

Last Thursday evening was clear here although there was a bright Moon.

I obtained images of several comets and the field of C/2018 A1
(PANSTARRS). The faint fuzzy object at the centre of the attached image
is several arcmin south of the predicted position but the last published
orbit was in MPEC 2018-A43, dated Jan 11. This was based on a relatively
short arc. I've sent my astrometry to the MPC and if this really is the
comet then the orbit changes quite a bit from the one published on MPEC
2018-043.

Has anyone obtained astrometry of this comet recently? It is supposed to
be around mag 18.

Nick.
