U Gem
From early February 2002, several observers reported a slight brightening
(~13.6 mag) of U Gem (vsnet-campaign-dn
2109). The object remained slightly active until February 13 (vsnet-campaign-dn
2113, 2119),
and then, an outburst was detected on February 14. The Kyoto team observed
eclipses just before and during the rapid rising stage (vsnet-campaign-dn
2120, vsnet-campaign-ugem
1). The rapid rising was confirmed by visual observations on February
14 - 15 (vsnet-campaign-ugem
2, 3,
4,

8,
9,
10,
11,
12,
13).
The object reached the peak on February 15-16 (vsnet-campaign-ugem
14, 15,
16).
It then faded from the maximum of the outburst (vsnet-campaign-ugem
17, 18,
19,
20,
21).
After this outburst, on May 1, M. Simonsen's observations showed short-term
modulations, which may imply another active phase (vsnet-campaign-ugem
22).
An outburst was reported by T. Kinnunen and R. Stubbings on December 21.
The outburst interval may be relatively long (vsnet-campaign-dn
3168, 3171,
3188,
3207).
