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.
