Swift detection of a serendipitous source close-by to SN 2009ip
Abstract
Swift X-ray Telescope (XRT) observed the Type-IIn SN 2009ip for 45 ks. The observation campaign started on Sept. 4, 2012, well in advance of the important changes in the spectrum firstly detected on Sept. 15-16, 2012 by Smith & Mauerhan (2012, ATel #4412). SN 2009ip is not detected in the summed image with an upper limit of 5.67x10^{-4} c/s (obtained with XIMAGE/sosta). This improves the limit by Margutti et al.
