AQ CANIS MINORIS
V-band photoelectric photometry by A. Shambrook with the CTIO
1 m telescope shows superhumps in the light curve of this recently-
erupted dwarf nova. Timings on February 12 and 13 indicate a
period of 95.9+-0.3 minutes. The amplitude (0.17 mag peak-to-
trough) and waveform (fast rise, slow decline) are normal for SU UMa
stars in early decline from a superoutburst. On February 13 the star
was at V=14.5.
CCD observers can perhaps follow this star as it gets considerably
fainter, and look for the "echo" signature (after a sharp fading to
near quiescence) that is often seen in this class of dwarf novae.
That would be awfully interesting, as would its (certifiable)
absence!
