Please continue V2837 Ori

   Josch Hambsch has been reporting observations of
V2837 Ori.  The object is currently (almost)
"heartbeat state" with a cycle length of 30-40 d.
See paper by Kimura-san on IW And-type stars
https://ui.adsabs.harvard.edu/abs/2019arXiv191207217K/abstract
for the description of this state.

   Observations of eclipses are very important
to measure the variation of the disk size
throughout the entire cycle of a heartbeat.
Higher time-resolved photometry targeting eclipses
are also very welcomed.
