[vsnet-alert 2133] V592 Her linearly fading

[Taichi Kato <tkato>]

V592 Her linearly fading

  Nightly averages of Garradd's CCD time series indicate V592 Her is linearly
fading, as is usual for a superoutburst.  The average rate 0.21 mag/day is
significantly larger than usual SU UMa type dwarf novae.

   980830.421 14.138 0.116 130 GAR
   980901.392 14.581 0.065  10 GAR
   980902.418 14.757 0.107 194 GAR

  (The zero point of mean magnitudes are rather arbitrary; these calibrations
seem to give slightly fainter magnitudes than visual estimates).

  Masi's CCD observation on Aug. 31 seems to safely preclude large-amplitude
superhumps.
