[vsnet-obs 3224] slow decline of the standstill of RX And

[Taichi Kato <tkato>]

   One of our colleagues, Tsutomu Watanabe (VSOLJ), has pointed out the
recent trend of slow decline seen in the light curve of RX And, which
is presently experiencing an unusually long standstill.

   The table below shows monthly averaged visual magnitudes from vsnet-obs
observations.  The trend is evident.

   Does this phenomenon indicate decreasing mass-transfer from the secondary?
May this standstill cease shortly after this?
