[vsnet-campaign-dn 2071] SX LMi: superhump evolved!
SX LMi: superhump evolved!
Our last night (January 23) observation detected fully grown
superhumps with the increasing amplitude from 0.3mag to 0.4mag within
three cycles.
Our preliminary period analysis yielded the best period of
0.07088(24) d, which is significantly longer than that reported
in Nogami et al. (1997) (0.06950(2) d). While the base line of
the current light curve is very short, it may indicate a rapid
period decrease within this few days.
The general fading trend was seen in the light curve on January 22,
but the trend has stopped or the object has rebrightened between
these observations.
