The New Milky Way: a wide-field survey of optical transients near the Galactic planeKirill Sokolovsky, Stanislav Korotkiy, Alexandr LebedevCurrently, it may take days for a bright nova outburst to be detected. With the few exceptions, little is known about novae behaviour prior to maximum light. A theoretically-predicted population of ultra-fast novae with t2<1d is evading observational discovery because it is not possible to routinely organize fast follow-up observations of nova candidates. With the aim of brining the detection time of novae and other bright (V<13.5) optical transients from days down to hours or less, we develop an automated wide-field (8x6 deg.) system capable of surveying the whole Milky Way area visible from the observing site in one night. The system is built using low-cost mass-produced components and the transient detection pipeline is based on the open source VaST software. We describe the instrument design and report results of the first observations conducted in October-November 2011 and January-April 2012. The results include the discovery of Nova Sagittarii 2012 No. 1 as well as two X-ray emitting cataclysmic variables 1RXS J063214.8+25362 and XMMSL1 J014956.7+533504. The rapid detection of Nova Sagittarii 2012 No. 1 enabled us to conduct its X-ray and UV observations with Swift 22 hours after discovery (~31 hour after the outburst onset). All images obtained during the transient search survey are available online.
За сегодня странный блеск у полуправильной переменки типа SRB - V1048 Her, блеск 14.84 при диапазоне из AAVSO(VSX) - 17.9 - 19.3
При сьемке без L фильтра - так и должно быть, а вот с L - это было бы уже интересно.
ОК, диапазона по R я не видел, звезда красная, так что наверное все в порядке.
