Memory Management

The SSR is emptying each day.

Data Gaps

GAPS IN APP_ID = 102 (VC3-MONITOR RATES) WITH PACKET RATE LT 30

These data were later located and are being reprocessed now.

Operations

A spin up was performed Aug 16. Current spin rate is 14.94 rpm. Normal/vigorous decimation. No events during eclipse or north/south magnetic zones. We agreed to temporarily take events during eclipse for at least a few days to see if we can still empty the SSR. It will be at the Operator / Tohban's discretion whether to turn off these events.

A livetime issue was discussed. Since about 1 month after the anneal, the livetime averages (fronts and rears) have dropped to about 60%. The most likely reason for this is that livetime drops to 0 during nights since we are no longer taking events. Jim will try to adjust the livetime calculation so that it does not include zeros.

Other notes

The AGU abstract deadline is Sept 2.
