[vsnet-alert 14657] Re: SDSS J172102.48+273301.2

[Denis Denisenko]

MASTER-Kislovodsk robotic telescope (http://observ.pereplet.ru/)
observed this area on 2012-06-05 at 23:24:38 UT and 23:57:00 UT but
has not produced the transient alert because it was only imaged by one
of two 40-cm f/2.5 tubes (the Western one). Judging from CRTS and
MASTER data, the outburst has started somewhere between May 27th (the
latest CRTS image of the object at  quiescence) and June 05.

20120605.975  16.20C  MASTER-Kislovodsk
20120605.998  16.04C  MASTER-Kislovodsk

Internal photometry errors are 0.07m (SNR=13).
