[vsnet-alert 17166] SDSS J090221.35+381941.9 rebrightening confirmed

[Denis Denisenko]

Last night I have finally got my request on this object fulfilled by
the Bradford Robotic Telescope, and the variable was at the same level
as during the last 9 days since March 29. Following the report in
[vsnet-alert 17164] I have pointed MASTER-Tunka at this position
(MASTER-Amur is clouded out). Despite the poor limiting magnitude
(thin clouds), the brightening of the object is obvious! The following
magnitudes were measured from unfiltered CCD images using AAVSO
sequence (143 comparison star, 149 reference star).

SDSS J090221.35+381941.9
  20040406.9072  16.92CV  BRT
  20040407.5924  14.74CV  MASTER-Tunka

That would make a 3.2 mag/d brightening rate over the last 16 hours.
