We obtained 1 ks XRT observation of the Crab Nebula in the windowed timing (WT) mode starting at 2010-09-22 16 42 44 UT. A preliminary analysis does not reveal any significant change in the source flux and spectrum compared with previously detected values (see, e.g., Weisskopf et al., ApJ, 713, 2010 and references therein).X-rayGamma Ray>GeVNeutron StarsPulsarsSupernova Remnantshttp://adsabs.harvard.edu/abs/2010ATel.2866....1E2010ATel.2866....1E
