Swift detects a strong increase in the X-ray flux of V2468 Cyg
Abstract
Swift observations of V2468 Cyg in August and October 2011 (days 1266 - 1322 after outburst) revealed a super-soft X-ray spectrum (ATel #3754); at that time, however, there was no noticeable change in count rate from the previous spectral state which had shown both hard and soft spectral components since the first Swift observation in June 2009 (~460 days after outburst). A further monitoring campaign was begun at the start of June 2012 and observations between 01 June and 13 July (days 1547 - 1589) showed similar spectra to those obtained in autumn 2011.
