SOHO Daily Meeting Minutes for Wednesday 2 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 will be on Thursday. * We are getting Medium Rate telemetry through the Low Gain Antenna (LGA) on the 34 meter pass (D65), using D66 for uplink. So far, we have been unable to acquire high rate on the 34 meter stations using the LGA. The DSN schedule is fixed for this week but next week's schedule is being reworked to get us as much contact as possible. At some point this week (Thursday, TBC) we expect to start using the SSR to record short periods of science data during non-contact periods, at times chosen by VIRGO. * We plan to do a momentum management, 180 degree roll, and a station keeping 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 the weekly meeting tomorrow. Fuel estimate is 0.01935 kg. * Daily 34m passes: Wednesday: D66 13:00-17:00 26-meter for uplink D65 13:00-17:00 D/L only Thursday: D34 00:20-04:20 D24 15:00-19:00 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 * CNE network outage from 6-8pm on Wednesday 2 July. CNE internet access, e-mail services and building to building traffic will be intermittent. * 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.
