MM Sco: new SU UMa-type dwarf nova!

Dear Colleagues,

   Berto Monard took time-series CCD photometry of MM Sco (currently
in long, bright outburst) on Sep. 10-11, and just sent us the data.
The data clearly shows the presence of 0.1 mag humps, which are most
likely superhumps!  A preliminary period analysis suggests that the
superhump period is around 0.062 d.  Further time-series CCD photometry
is most urgently requested in order to firmly establish the classification
and the period.  (The presence of a close neighbor companion may have
somewhat reduced the above reported amplitude).

   For readers interests, past calls for observations of MM Sco can be
found in vsnet-alert 946 and vsnet-campaign 305.

   Congratulations, Berto!

Regards,
Taichi Kato
