SX LMi [UGSU, 13 - 17.4V]
=========================
Tonny Vanmunster, Landen, Belgium reports his visual detection of
an outburst of SX LMi, a UGSU-type dwarf nova, which is part of the
CVAP. The outburst has been secured on CCD image.
1996 Jun 03.938 UT, 13.2 (T. Vanmunster, 0.35-m refl., seq: GSC);
Given the observed brightness, chances are high this is a super-
outburst of SX LMi.
The object is located at : R.A. = 10h54m30.49s, Decl. = +30d06'09.3"
(J2000.0). A finder chart and sequence are available on the
Cataclysmic Variables Home Page.
SX LMi was for the first time identified as an SU UMa type dwarf nova
by the Ouda Team at Kyoto University, Japan, in December 1994. Their
observations revealed superhumps with an amplitude of approx. 0.3 mag.
Preliminary reductions gave as a best estimate for the superhump
period a value of 100 min.
According to data listed in the Outburst Activity Database on Selected
Cataclysmic Variables, SX LMi was last reported in outburst on March
18, 1996, by Lasse Jensen, Denmark, when it reached mag. 13.5 [CVC 87].
