[vsnet-obs 46396] U Gem on 2003 Aug 17 UT (GRL, NAS.VSS).


Norwegian Astronomical Society - Variable Star Section

Variable Star Observations for 2003 Aug 16-17 UT (J.D. 2442868)

Observer: B. H. Granslo (GRL).
Location: Haagaar Observatory, Eina, Norway.
Instrument: 25.4-cm f/6 reflector + ST-6 CCD camera (M254+CCD).
Observations: CCD with V-filter, differential photometry.

Variable   YYYYMMDD.DDD  Magn  Obs  Instrum.  Mag.ref.  Codes Estimates
GEMU       20030817.080   9.8V GRL  M254+CCD   NAS.VSS  YBKL  Comp. B, C

Notes: U Gem appeares to be in outburst. Comparison stars (from NAS.VSS
  sequence): B = HD 64535 (V = 8.63, from GCPD), C = HD 64071 (V = 8.95,
  from ASAS-3). Deduced V-magnitude is somewhat uncertain (estimated
  accuracy +/- 0.1 mag.) due to low altitude (7-8 deg.) and nautical
  twilight. Observation is corrected for airmass differences between
  variable and comparisons.

                              Yours sincerely,
                              Bjorn H. Granslo
