In the General AAVSO Discussion forum, Sebastian Otero requested photometric monitoring of the imminent secondary eclipse of V0795 Cas:


The eclipse is anticipated to begin this Sunday, July 31, at 17:08 UT, and end around Wednesday, August 3, at 04:35 UT.

Sebastian says:

"Multicolor observations should be critical now to see the amplitude in the different passbands. The eclipse will be challenging. so it is important to have dense coverage a couple of days before and after it to see if it can be glimpsed.
Then, weekly observations until the primary eclipse in September might be useful too"

Therefore, I would like to request an initial period of intensive coverage beginning immediately, and ending on or after August 6th. After August 6th, a reduced cadence of 1-2 observations per week continuing through September 10th could be beneficial.

The use of multiple filters during each observation is encouraged. I band is of the highest priority, followed by R band, then V, and finally B. If all 4 can be obtained during each observation, that would be ideal.

Reduced data will be uploaded to the AID.
