AK Cnc [UG, 13p - <17p]
=======================
Several independent reports have been received telling about an outburst
of the dwarf nova AK Cnc, which is one the Recurrent Objects Programme
of The Astronomer. Steve Howell, Planetary Science Institute, Arizona
points out that AK Cnc is a suspected TOAD (Tremendous Outburst Amplitude
Dwarf nova) and that follow-up photometric (and spectroscopic) observations
are encouraged. The following table depicts the course of the present
outburst, which might be a superoutburst :
1995 03 07.892 UT, [14.5 (G. Poyner, UK, 0.40-m refl., seq: TA);
03 08.813 UT, 13.8 (L. Szentasko, Hungary, 0.33-m refl.);
03 09.001 UT, 12.8 (B. Worraker, UK, 0.26-m refl., seq: TA);
03 09.021 UT, 12.8 (B. Worraker);
03 09.038 UT, 12.7 (B. Worraker);
03 09.060 UT, 12.8 (B. Worraker);
03 09.082 UT, 12.8 (B. Worraker);
03 09.811 UT, 13.2: (J. Pietz, Germany, 0.20-m SCT);
03 09.876 UT, 13.2 (P. Schmeer, Germany, 0.20-m SCT, seq: AAVSO);
03 09.914 UT, 13.2 (J. Pietz);
The previous outburst of AK Cnc was detected by Bill Worraker, UK on
April 8th, 1994. The object reached magnitude 14.3 during the outburst.
