[vsnet-alert 16457] MASTER OT J015016.17+375620.5 unusual behavior

[Denis Denisenko]

After the Sep. 16 outburst reported in [vsnet-alert 16406] this X-ray
selected CV in Andromeda was observed with the Bradford Robotic
Telescope almost every night showing interesting behavior. The object
has quickly faded, however not to the minimum level (~19m), but only
by ~1.5m. On the last night it started rising again, brightening by
0.6m since Sep. 24.

The object's nature is still unclear. It may be a dwarf nova of ER UMa
type, or a very active polar. Hopefully, measuring the orbital period
can shed some light on it. Time series are very desirable!
