Notes from 9am meeting ---------------------- Ops: - Supports Completed: 3 (3 34 Meter, 0 26 Meter) - TECH DR's Created: During this support w/DSS-27, command lock status on LGA-A showed "no lock" yet commanding was not impacted. This was after an LGA swap from B to A; however, command lock status for LGA-A was showing "no lock" before the swap as well. LGA-B showed command lock for the entire support. Four CNOOP1s were issued and a small dropout in telemetry would ensue after each. All four CNOOP1s did receive good command counts and command rejects on both sides. This looks like similiar issues we have had DSS-27 in the past except for this support was at a low altitude (47-65 kkm). The next support was with the same station (DSS-27) and had no issues with command lock. - SSR Dumps: 3 - Current Configuration (as of 123/1300): In Radiation Zone NO Current SI HRC-S Grating LETG Observation ID 08899 Target Xi Boo Altitude 119.2 kkm Asc Radmon Disable 124/23:40z Next Radiation Zone 125/00:16z to 125/12:06z - Next Scheduled Supports (7): Time BOT EOT Site Station Antenna 123/1940-2230 2020 2220 MADRID DSS-66 26 Meter 124/0210-0500 0250 0450 MADRID DSS-66 26 Meter 124/1200-1415 1300 1400 GOLDST DSS-24 34 Meter 124/2000-2150 2040 2140 MADRID DSS-66 26 Meter 125/0300-0450 0340 0440 MADRID DSS-66 26 Meter 125/1510-1745 1535 1735 MADRID DSS-66 26 Meter 125/2115-2330 2215 2315 GOLDST DSS-27 34 Meter MP: - MAY0508A products were approved. Eng: - The LGA cmd lock issue is likely a case of no good angle immediately after the LGA swap and not a cause for concern. Radiation: - Solar Activity Forecast: Solar activity is expected to be very low. - Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled with isolated active periods for the next three days (01-03 May). Elevated activity expected on day one is in response to the CME observed on 26 April. Activity on days two and three is in response to a recurrent coronal hole high speed stream that is expected to rotate into a geo-effective position.
