MisV1448
Enrique de Miguel reported:
On average, 0.68 mag fainter than yesterday. Looks
like fading at a constant rate of ~0.028 mag/h, which is
consistent with the observed decrease of 0.17 mag
over tonight's 6-h long run. Mean amplitude is 0.021 mag
(curve fit the data).
Considering an ANOVA analysis, the main period when
combining this and yesterday's run is 0.169(5) d, but
other alias cannot be ruled out using just 2 runs from
a single site. I'll keep an eye on this target over
the coming nights.
Variability type still unclear.

The decline rate of 0.68 mag/d seems to be to slow for
an ordinary SU UMa-type dwarf nova.
