C/2009 F1 (Larson)
Using G1 22-Mar-2009, 09:57:55 - 10:16:38 UTC.
RA 12:36:42.70 Dec -01:36:26.0.
Clear, R, V & B filters 300 sec each binning 1:2:2:2.
The seeing was not particularly good, and left a bit late in the day for a good capture (alt ~ 39 deg, air ~ 1.6). The gif has been cropped to about half of 1 minute square. Apparent nuclear magnitude is 19.27 (source JPL/HORIZONS).
My measurements were 16.023 V mag
