* We expect to lose the high gain antenna link today (or at least not be able to reacquire it on tomorrow's 34 meter pass). We no longer have it on 26m stations, just on the 34m stations. Once we lose the high gain antenna link on the 34m stations, the spacecraft will be transitioned to low rate.
We have daily passes on 34 meter stations for monitoring and commanding of the spacecraft. The 34 meter schedule for this week is included below. Since the times are very limited, we'd like to request that ALL TEAMS BE AVAILABLE (at EOF or by phone) during the passes, in case your instrument comes up in an unexpected state. When downlink only 34 meter stations are scheduled, a 26 meter station will be used for uplink (i.e. all 34 meter passes will have commanding capability).
Week 26 34-Meter Passes
BOT EOT -------------- Fri DSS-54 13:00-17:45 UT Sat DSS-24 17:35-20:35 UT Sun DSS-54 13:00-17:30 UT
* Current RHESSI default target is AR10391. When selecting this target to maximize coordination w/others, use campaign number 6850.
* There will be about 10 UMD physics engineering students visiting the EOF through the Goddard Outreach Program today at 11:15 AM. POC: Bob Dutilly.
