[vsnet-alert 594] rapidly growing eclipses of V651 Mon

[Taichi Kato <tkato>]

Dear colleagues,

   V651 Mon (central star of NGC 2346) continues to show rapidly growing
eclipses as indicated by the following observation reported to vsnet-obs.
The star was mostly brighter than V=13 only three or four orbital cycles
earlier.  Gray Poyner's latest observation seems to indicate the ingress
and egress of eclipses are very steep, implying a steep density gradient
of the suggested cloudlet passing in front of the binary.
