Previous outbursts have not been well covered so the exact nature of
the system is unknown. Two types of outbursts have been identified in
archival searches. Based on this, Wenzel (IBVS #3440) suggest it is a
UGSU system but subsequence photometry by Kato (IBVS #4757) was not
conclusive. Schmeer et al. (IBVS #4758) suggest it is a UGSS system
with long and short outbursts based mainly on its relatively red color
compared to typical UGSU systems.
From Schmeer et al.: "The 1940 eruption was a bright outburst, which
lasted more than 18 days. The 1986 outburst listed by Wenzel was also
bright, but of unknown duration, while the 1999 outburst was
definitively fainter and shorter (5...7 days). The 1963 and 1966
outbursts were also faint, but too fragmentarily observed to permit
any conclusions on their character."
Outbursts tend to be short, lasting only a few days. But past
outburst coverage is incomplete so anything can happen. Stay sharp!
The orbital period of the system is not known and Kato reported
periods from 0.05d-0.015d. So there is lots to learn from consistent
and careful time series observations of this system.
Please use a V filter if possible
and set exposures times for an SNR of 100. Time resolution is
not as important as precision at this point. However, the system is
faint so you can observe unfiltered if that is needed to get an SNR of
100.
