[vsnet-alert 187] GO Com variability

[tkato@kusastro.kyoto-u.ac.jp]

    As notified earlier, dwarf nova GO Com is undergoing a long-lasting
post-outburst brightening.  Nightly averaged magnitudes obtained at Ouda
Station (Kyoto University) are:

  mid-UT     V-C   S.D.   N band
--------------------------------
950731.445  0.786 0.099   9 V
950801.447  0.719 0.141   5 V
950803.467  1.037 0.046  34 V     V=13.8

  C = GSC 12.8 (125636.64 +263142.9 J2000.0)

  The present rate of decline (~0.1 mag/day) seems to be characteristic
to a superoutburst.  Although very preliminary, Aug. 3 data seems to
suggest existence of variation of ~0.1 mag.  A broad maximum possibly
occurred around Aug. 3.473 UT (superhump?), but not conclusive because
of the short duration (~40min) of the observing run and the bright sky
background.
