. Attached is the discovery image of SN1999by. It is a 30 second exposure with the 30cm SCT and Starlight Xpress camera. The discovery was confirmed by Tom Boles and Mark Armstrong and looks as if it could be very bright. Although the weather has been very poor, I have managed over 1500 observations in April.

XMM-Newton Science Analysis System . ... CORR_RATE - The count rate after the following corrections have been applied; . 1) A further point-spread function correction may be applied, to extrapolate the counts from 12 to 35 pixels (presently only done for UV observations) 2) Correction for dead-time. 3) Correction for the OM sensitivity-degradation. A key-word TDS_CORR is added to the table to record the correction value. ... XMM-Newton SOC/SSC -- 2005-08-16 ...
