    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.

PS. Bye the way, Tonny, would you please avoid using hardward tabs, since
    tab settings may be different in different terminals or softwares?
    Some e-mail gateways even seem to remove hardware tabs by default;
    in these cases your precious observations may not be read as they
    should be.
    Thank you for your cooperation.
