Performing outbound CTI measurement, then perform two calibration observations of the white dwarf HZ43 to monitor the low energy response of the HRC-I (obsids 1001 and 1005). Dark moon observations take place late tonight. Replan underway for 2 Target of Opportunity observations of the dwarf nova WZ Sge, to be done this week: 20 ksec with HRC-S/LETG (2504) and 5 ksec with ACIS-S/NONE (2508). The plan is to intercept the current load during the 'DQ HERCULIS' observation (obsid 1899) at 208:0244. The ACIS observations of the moon will not be affected. Current ACE solar proton flux levels are low (under 50). Kp is 2.3.
