The latest outburst of RU LMi occurred in 1996 Jan. (detected by Tonny
Vanmunster).
Info from [vsnet-obs 1992] (1996 Jan. 16)

Regarding Tonny Vanmunster's outburst observation of RU LMi, I would
like to add some information of this dwarf nova from the discovery paper
(sorry I don't remember the name of the original reference).
RU LMi was discovered as a variable faint blue star (Ton 1143) at
Tonantzintla Observatory. The following magnitude estimates were reported.
date mpg
------------------------------
1955 Mar. 13 19.5 (POSS)
1957 Jan. 27 17.4
29 14.6
1958 Jan. 13 16.5
20 13.8
1959 Jan. 13 [17.5
14 14.8-14.7
15 14.7
19 [16.0
29 [17.5
These values may suggest a rather high outburst frequency. Is this
consistent with the results of recent monitoring? Quiescent photometry
and spectroscopy are given in Howell et al. 1990 (PASP 102, 758) and
Mukai et al. 1990 (MNRAS 245, 385), respectively.
