Swift detection of the fast turn-on of the recurrent nova M31N 1963-09c as a supersoft X-ray source
Abstract
The recurrent nova (RN) M31N 1963-09c has been detected as a supersoft X-ray source (SSS) with the Swift X-ray telescope (XRT) only 17 days after its most recent outburst. Swift has been monitoring the nova in a target of opportunity program with a two day cadence since about 6 days after the first optical detection on 2010-10-30.70 UT (ATel #3001). In an 8.2 ks observation starting at 2010-11-17.09 UT (ObsID 00031861007) the RN was clearly detected with (3.2±0.8)e-3 ct/s (corrected for PSF, sampling dead time and vignetting).
