1051+50 CY UMA 2450882.5180 1998-03-10 0.0180 12.93,
CY UMa data. Smooth. No sign of superhumps in a 4 hour time series at
the first night of the outburst.
0909-06 MM HYA 2450882.2854 1998-03-09 0.7854 14.62,
MM Hya time series (4.5 hours). Clearly showing superhumps with
amplitude 0.2 mag. I used a mag 14.8 GSC star for
comparison. Compared to other observers my mags are about 1 mag fainter.
This must be caused by different
sequences used.
Regards
Lasse Teist Jensen (JLT)
