SDSS J090221.35+381941.9: rapid fading
Enrique de Miguel has reported. I obtained a period
of 0.0334(1) d from the data during the rapid decline.
Outbursts in AM CVn-type objects may be different
in behavior from hydrogen-rich CVs and we cannot expect
what happens next.
Comments: Started later due to clouds early in the evening.
Still superhumping, but rapidly fading at a linear rate
of 1.8 mag/day. The period of this single run is
shorter than the mean period in the previous days.
In this run, f=30.00 c/d compared to typical values
between 29.65 and 29.69 c/d found on JD 737-740
(analysis of days JD 741 and 742 to be done).
