Shift L3557. Start at 107:12:00 GMT = 08:00am 17 Apr EDT End 10:00am 17 Apr SOT Lead DAS (Times will be given in GMT on day 107.) PLAN ---- Continue running load APR1309C. Do obsid 10025, an ACIS-S observation of the ultraluminous X-ray source X41.4+60 in M82, to look for a relation between the spectral state and frequency of the quasi-periodic oscillations. Then do obsid 10903, a continuation of the deep ACIS-I observation of Tycho's supernova remnant, to study the Fe-rich ejecta and the structure of the forward shock. Then into perigee passage.
