FS Aur : Normal outbursts again

According to AAVSO News Flash No. 749, the ultrashort period dwarf nova FS Aur experienced an outburst. The reported magnitude (13.84V on Mar. 7.1811 UT) is one of the brightest ones. This object is peculiar in that no confirmed superoutbursts has been observed while it has one of the shortest known orbital periods among dwarf novae (vsnet-campaign 807). On March 8, the Ouda team performed photometry and reported that the object was apparently fainter than the R=15.1 mag star. The outburst seems to be a normal one (vsnet-campaign 808). The next outburst was reported on September 29 by M. Simonsen at 14.1mag (vsnet-campaign-dn 1657). The object was reported to be still in the outburst at least on September 30 (vsnet-campaign-dn 1666).

T. Krajci reported a 0.4-mag sinusoidal pattern in the 3-hr light curve obtained on December 18 (vsnet-campaign-dn 1988). An outburst of 15.5mag was then detected by G. Poyner on December 21 (vsnet-campaign-dn 1999).
