Hi all
I'm actually going to try this remotely tonight/early am (local time) from
H06 in a FOV of 155.8 x 233.7 arc-mins, however I'm so used to using the
MPC one line that on this occasion without it on MPC (can't seem to locate
it) I will have to also rely on the MPC latest ephemeris for this object
just using the RA/DEC.
I'll let you know how I get on
Kind regards
Wendy
