V2837 Ori: behaving differently from before

   Many people have contributed to this campaign.
The object experienced a dip on Feb. 18-19,
and now it appears to be in almost constant phase
(of course, outside the eclipses) in contrast to
previous events.  In the past, the object gradually
brightened to the next "outburst", which is typical
for heartbeat state of IW And stars.
If the past periodicity of outbursts still holds,
the object should undergo a next outburst
within several days.  If it doesn't, we may be
observing a different state.
