[vsnet-campaign-dn 3618] V2527 Oph: data from Berto Monard



V2527 Oph: data from Berto Monard

Dear Colleagues,

   We have received from Berto Monard a long (about 6 hr) run on May 4-5.
The object was rather monotonously fading during this observation.
The mean fading rate was 0.70 mag/d, which is not characteristic of
those of SU UMa-type normal outbursts, although there remains a possibility
of the effect of a nearby companion.  No period modulations larger than
0.1 mag were observed.

   The current outburst of V2527 Oph was atypical, especially if it
finally turns out to be a normal outburst, in the it recorded the
brightest magnitude, probably surpassing those of "claimed" superoutburst(s)
in the past.  Since there is no solid publication on this type
classification, we probably need to re-examine the classification
of this star.

Regards,
Taichi Kato
