Dear Colleagues,
we managed to get a run 2.5 hours long on this star, with
the 0.8m telescope of the "Osservatorio Astronomico di
Campocatino", Italy. The time resolution was 21 seconds,
with an integration time of 10 seconds. The resulting light
curve is really excellent, showing a very remarkable
behaviour.
It looks like there are QPOs or quite short-term variations
(but better analysis is needed). The curve is quite
irregular and the modulation is sometimes stronger, with
more defined profile and larger humps. We observed a major
peak around 19:10UT, and after this the star showed a
fading of 0.1 mag in 1.8 hours.
Further analysis will be performed later.
Regards,
Gianluca Masi, Franco Mallia
