[vsnet-alert 15268] MASTER OT J043254.33+205641.8 still bright

[Denis Denisenko]

This optical transient in Taurus was reported in ATel #4697 on Jan.
03, but remained unnoticed on this list. Maybe people have thought it
is a possible SN, however I strongly suspect it to be a dwarf nova in
superotburst. Outburst amplitude was about 7m (16.2m at discovery,
nothing to 23m in SDSS), so this may be yet another CV of WZ Sge type.

Recent observations with MASTER-Amur robotic telescope show it is
still in outburst, having faded by ~0.5m in 7 days:

Photometric time series are strongly encouraged.
