SX LMi: Superoutburst in January
M. Simonsen detected a bright outburst (13.2mag) of the SU UMa star SX
LMi on January 22 (vsnet-campaign-dn
2066). The light curve obtained by the Kyoto team on January 22 showed
a somewhat rapid decline of the object and possible double-peak modulations
(vsnet-campaign-dn
2069). The object remained bright even on January 23 (vsnet-campaign-dn
2070), and fully-grown superhumps appeared. M. Uemura reported the period
of superhumps to be 0.07088(24) d, which was significantly longer than
that reported in Nogami et al. (1997) (0.06950(2) d) (vsnet-campaign-dn
2071). The object further brightened on January 24 (vsnet-campaign-dn
2076), and then started a normal gradual fading. M. Uemura reported
the shortening of superhump period (vsnet-campaign-dn
2078, 2079).
After temporal short plateau without any fading around January 30 (vsnet-campaign-dn
2080), the object again started gradual fading (vsnet-campaign-dn
2081, 2082).
Superhumps decreased in amplitude with time (vsnet-campaign-dn 2087).
The rapid fading from the superoutburst was reported on February 4 (vsnet-campaign-dn
2093, 2094).
The superoutburst finished and no major rebrightening was detected (vsnet-campaign-dn
2072, 2122).
An outburst of 13.5mag was reported by M. Simonsen on December 3 (vsnet-campaign-dn
3070).
