[vsnet-alert 16549] MASTER OT J015016.17+375620.5 bright outburst!

[Denis Denisenko]

This very unusual cataclysmic variable in Andromeda is at its
brightest state since I started my observations of it with the
Bradford Robotic Telescope.

Note: I was using 14.1m for the nearby reference star marked as 145 on
AAVSO chart 12731ANX.

The LC looks very interesting. As I wrote before, it reminds that of
ER UMa variable, but it also had the prolonged low states in the past.

For the third time I call for the time-resolved photometry of this
object. No response was received after the announcement of outburst in
[vsnet-alert 16406] and unusual behavior in [vsnet-alert 16457]. Eddy
Muyllaert has also noted the strange behavior (standstill???) in his
message to cvnet-outburst on Oct. 18. And now the star *has*
brightened! The Moon will be more than 50 degrees away tonight, in
Taurus or even in Orion.
