PLAN
----
Continue running load MAY0106C. Do obsid 6923, an HRC-S/LETG
calibration observation of the BL Lac object PKS 2155-304. Then obsid
6934, an ACIS-S observation of the cluster Abell 2597 to study the
"tunnel" driven into the X-ray gas by radio outbursts. 

Next Comms:
121:1845 to 2045
122:0240 to 0340
122:1245 to 1345
122:2150 to 2250
123:0200 to 0300
123:1120 to 1220 
123:2020 to 2220 
124:0345 to 0445

NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
Nine supports over the weekend. Three SCS segments were loaded, on-board
loads good until 125:06:52. 
MAY0806 products are expected out today for load review tomorrow.

Radiation levels are low (< 50) but slowly rising.  Solar Activity
Forecast: Solar activity is expected to be low. M-class flare activity
remains possible.
