DM Dra: Long bright outburst on October

P. Schmeer reported a rare outburst of DM Dra, a large amplitude dwarf nova. The magnitude reached 14.1 on October 18 (vsnet-campaign-dn 213). T. Kato commented that the object had been monitored visually for several years, but there was no confirmed outburst reported to VSNET, except two suspected sightings by T. Kinnunen (1998 Sep. 25, 16.0: and 2000 Sep. 30, 15.9:). The brightness and the duration of this outburst very strongly suggest a superoutburst (vsnet-campaign 538). T. Kato performed the photometry of the time-series data on October 27, observed by K. Matsumoto, the Kyoto team. The observation covered only 0.091 d and there is a hint of a maximum during the early part of the observing run. However, the amplitude of superhumps (if exists) did not much exceed 0.1 mag (vsnet-campaign-dn 243).
