* All but completed queue applies to GBT only proposals
Current backlog of Reg & RRS proposals [hours prior to 08A*] = 1197
[2005:63(5), 2006:194(10), 2007:940(43)]
Backlog includes 73 hrs of monitoring projects
274 hrs of vlbi projects
Total time to discharge [hours] = 4241
Includes 119 hours++ of monitoring (not Large or Spec) after trimester 08A
1629 hours of Regular & RRS proposals
2291 hours of Large proposals
322 hours of VLBI proposals
* Includes projects that are on hold for trimester 08A
++ Time is counted in other break down as well. 08A
There was some concern that we would not be able to execute some key science projects if we were not able to repair the elevator and execute 2 receiver removals and 2 receiver installations. Do to the hard work of many, some good weather, all was done as we had hoped.
We supported 22 projects in 31 observing sessions. The telescope was also scheduled for 16.5 hrs of maintenance. Lost time was low -- 4.6 hrs or 3% -- and was due mostly to the weather.
- Freezing rain - 2.4 hrs
- Winds - 2 instances - 0.6 hrs
- Active Surface - 2 instances - 0.3 hrs
- Wrong VLB scheduling block - 0.3 hrs
- Bad Pointing due to weather - 0.3 hrs
- Servo Turret - 0.3 hrs
- GFM - 0.2 hrs
- Spectral Processor - 0.2 hrs
- Az Transducer Fault - 0.1 hrs
As I suspected, the lost time reported last week was misreported and was high by about 1 hr.
Both Zpec and Mustang are off the telescope after very successful first season observing.
GBT Telescope Operations -- Bob
Both elevators are available for operation again. The rest of this week's maintenance time was consumed by receiver changes.
- This week we first removed Mustang, Zpectrometer, and then installed C band and Ku band receivers.
- The receivers are ready for use.
- Completed the replacement of a pin diode switch in CM15. Qualified for use.
The "sense" of wind directions has now been corrected and verified to indicate winds "OUT OF" any given direction.
RFI Group Operations -- Carla
- Mostly normal tracking. Tracking shutdown on April 1 at 9:30 PM. Pete cleared the 43m for motion after a system check. Tim Weadon is examining.
- Plans continue to be developed for Front End and Trailer upgrades.
- MIT/LL requested that we take the low frequency feed off on Monday April 14. Rx Box should be put in the 43m control room.
- Accomplishments:
- Dana worked with the software group on the statistics plots, fixing a few minor bugs and understanding the code.
- The overall look and feel of the project pages has been greatly improved
- Work on completing the project database was begun
- Version 0 of the user's manual was completed
- The project team was expanded to include Jules Harnett (Jim Braatz joined two weeks ago)
- We are now the full, desired team size for the summer tests
- Upcoming
- The user's manual will be changed in response to comments
- The projects interface will be completed by Friday of next week for release to the project astronomers
- The full database will be completednext week and updated with all backlog projects
- Concerns
- 8 more weeks to go
MUSTANG -- Brian
- Team meeting and updates on summer MUSTANG work
- MUSTANG safely removed from telescope.
- Development of instrument failure scenarios and mitigation/restoration/escalation plans
- Upcoming items:
- MUSTANG to return to UPenn 10-April
- Develop contents and planned dates for summer MUSTANG/YGOR releases
PTCS program -- Marty
- Servo replacement spec development
- Active Surface actuator repeatability and surface error tests
- System Design and Modeling small group meetings
- Upcoming items:
- Sponsor testing of Holography Manager
- OOF Holography
- Status telecon to be held later this morning
CICADA program -- John
- GUPPI
- Got spectra out of it and onto disk this week. Maybe Scott or Randy has an update?
- Worked through a bunch of little problems, got fast help from Wolfgang when needed!
- Nothing else on CICADA
- The Zpectrometer was removed from the telescope on April 2.
- A target date for testing a single pixel receiver on the GBT needs to be addressed. (Late Summer?).
- The other components are progressing toward completing a single pixel as scheduled.
