SOHO Daily Meeting Minutes for Thursday 3 July 2003 ANNOUNCEMENTS ------------- * Note that Friday 4 July is a US holiday - there will be a student SOC in the EOF. There will be no daily meeting. The weekly planning meeting took place today. * We are getting Medium Rate telemetry on D24 (34 meter station) through the Low Gain Antenna (LGA). On the earlier 70-meter pass (D14), a partial SSR dump was performed; we now have about 3 hours 45 minutes available for VIRGO recording sessions. The DSN schedule has been updated for this week and next week's schedule has been reworked to get us as much contact as possible (there is always a potential for changes, though, hopefully for the better). The SSR is being used now to record short periods of science data during non-contact periods, at times chosen by VIRGO. * We plan to do a station keeping, momentum management, and a 180 degree roll maneuver on Tuesday July 8, with the SORR taking place on Monday after the 9am local staff meeting. The schedule is being worked out, and a draft will be sent out after today's weekly meeting. Fuel estimate is 0.01935 kg. * Daily 34m passes: Thursday: D34 00:20-04:20 D14 12:50-14:45 D/L only 70-meter antenna D16 12:50-14:45 26-meter for uplink D24 14:45-19:00 Friday: D24 15:45-19:45 Saturday: D14 16:55-00:35 D/L only 70-meter antenna D16 17:25-22:05 26-meter for uplink Sunday: D34 01:50-04:45 D24 13:35-17:00 * SSR Record Times: Thursday: 19:00 UT - 20:45 UT Friday: 10:30 UT - whenever the SSR is full Sunday: 11:00 UT - 13:35 UT Monday: 18:00 UT - 19:45 UT * Luis has created a new attitude file 'nominal_roll_attitude.dat' that will contain the value of the nominal roll angle of the spacecraft. It can be found at: http://soho.nascom.nasa.gov/data/ancillary/attitude/roll/nominal_roll_attitude.dat ftp://sohoftp.nascom.nasa.gov/pub/data/ancillary/attitude/roll/nominal_roll_attitude.dat so the instrument teams can begin testing the modifications to their software they may have to implement. Suggestions about format, etc. are still welcome. The exact time of the 180 roll on July 8 is unknown so the time field is set now to '00:00:00'. * Current RHESSI default target is AR10397. When selecting this target to maximize coordination w/others, use campaign number 6850.
