Currently descending toward perigee and secured for radiation zone. Next observation is at about 156:0400 GMT, a calibration observation with the HETG. Replan load uplink for TOO to be performed during this contact. Radiation is low, flux below 100. Very low probability of major solar flare activity.

Targeted for slots 128, 129, and 130., The first two loaded properly but the load in slot 130 failed. This is not an immediate problem since the successful portion will support operations for several days, but it is not clear at this point why the entire load could not be uplinked. 4) Continued problems with the GRETA workstation. Old computer had numerous problems of late. New computer (Compaq) installed, running Linux 7.2, but logs out/crashes autonomously. GOT believes the machine is not yet properly or fully configured.
