   The SU UMa-type dwarf nova AB Nor is undergoing its relatively
rare outburst.  Follow-up observations are strongly encouraged.

Past outbursts:
1997 Oct.  13.8
1999 May   14.7
2000 Apr 1  14.4 (precursor)

We suggest that AB Nor belongs to a rather rare class of long-period
SU UMa-type dwarf novae with low mass-transfer rates.
