List of 2011B programs for:
MegaCam,
WIRCam,
ESPaDOnS.
QrunID | Instrument | HST Dates | Number of Nights | Status | Run Summary | |
---|---|---|---|---|---|---|
11BQ01 | MegaCam | Aug 1 - 4 | 4 | Done | This is the continuation of the 11A run. Programs from 11A and 11B are executed during this run. Most of the nights were clear with good IQ. A few hours were affected by thin cirrus or IQ over 1 arcsec. | |
11BQ02 | WIRCam | Aug 5 - 15 | 11 | Done | The run was affected by high humidity and clouds, but when the sky was clear, the Image Quality was often around 0.6". | |
11BQ03 | ESPaDOnS | Aug 16 - 21 | 6 | Done | The first 4 nights were almost perfect, and the weather started to degrade on night #4. The last 2 nights were affected by clouds and high humidity. However, the run was very productive and lots of observations were carried. | |
Shutdown | Shutdown | Aug 22 - 27 | 9 | Done | This block of down time was used for re-aluminizing the primary mirror and doing some telescope maintenance. The QSO database was also offline while maintenance was performed. The shutdown ended up being shorter than 9 nights. | |
11BQ04 | MegaCam | Aug 28 - Sep 5 | 9 | Done | Only one night was completely lost to high humidity, otherwise, most nights were photometric. The telescope focus model had to be checked and re-adjusted after the modifications done during the shutdown. | |
11BQ05 | WIRCam | Sep 6 - Oct 19 | 44 | Done | During this very long run, about 1/3 of the nights were completely clear, 1/3 of the nights were mostly lost to bad weather, and the last third of the nights were a mixed bag of clouds and clear skies. | |
11BQ06 | MegaCam | Oct 20 - 30 | 11 | Done | The first half of the run had better weather conditions than the latter half, during which the skies were often overcast, or photometric but with an Image Quality above 1 arcsec. There were also technical issues with the declination axis encoder and MegaCam, and about 6 hours in total were lost. | |
11BQ07 | ESPaDOnS | Oct 31 - Nov 15 | 16 | Done | This run was severely affected by weather (high humidity and snow, clouds), and little progress was made for the programs that were attempted. | |
Classical | AOB | Nov 16 - 22 | 7 | Done | n/a | |
11BQ08 | MegaCam | Nov 23 - 30 | 8 | Done | The weather has not been much better than during the previous runs. | |
11BQ09 | WIRCam | Dec 1 - 14 | 15 | Done | More than half the time was lost to bad weather. | |
11BQ10 | MegaCam | Dec 15 - 16 | 2 | Done | One night was lost to a dome shutter drive failure. Then a glycol leak prevented observations on Dec 16/17. To give time for cleanup and investigation, WIRCam was put early on the telescope | |
11BQ11 | WIRCam | Dec 17 - Jan 2 | 17 | Done | Due to a technical issue, WIRCam was put back on the telescope. The weather improved significantly toward the end of the run. | |
11BQ12 | ESPaDOnS | Jan 3 - 16 | 14 | Done | The original 10-night run has been extended by 4 nights. The weather was excellent for the first 9 nights, then one night was lost to high humidity, and 3 other nights were affected by clouds. This run has allowed the QSO Team to catch up on most programs, even some that were initially scheduled for the November run. A and B programs are complete at 86%, which is excellent. | |
11BQ13 | WIRCam | Jan 17 - 22 | 6 | Done | Except for about one night of variable cloudiness, this last WIRCam run went very well, and the weather has allowed the QSO Team to make a lot of progress for the 11B programs that remained. | |
11BQ14 | MegaCam | Jan 23 - 29 | 7 | Done | An excellent run to end semester 11B! Except for a few hours of clouds and a night with high winds, observations went very smoothly. The conditions allowed the QSO Team to do some catching up with A and B programs. |
