QrunID | Instrument | HST Dates | # Nights | Status | Run Summary |
---|---|---|---|---|---|
Shutdown | Aug 1-5 | 5 | Done | The shutdown was completed one day earlier than our most optimistic schedule. | |
17BQ01 | ESPaDOnS | Aug 6-14 | 9 | Done | The first 3 nights were affected by clouds, but we observed nonetheless. The seeing stabilized more quickly than anticipated; only the first night had Image Quality uncharacteristically above 1 arcsec. On the second night, we were well below 1 arcsec as usual. |
17BQ02 | MegaCam | Aug 15-30 | 16 | Done | Despite 28 hours lost to bad weather (clouds or fog), this run was very successful. Besides 20 minutes lost to a filter jukebox issue, and an hour septn investigating network and computer issues, there were no other time lost to technical issues. |
17BQ03 | WIRCam | Aug 31 - Sep 4 | 5 | Done | One of the two WIRCam filter wheels failed on Sep 3; althought we were able to finish the night using only one filter, the issue requires warming up and opening the cryostat. The night of Sep 4/5 was lost to high humidity. ESPaDOnS will replace WIRCam for the remaining 6 nights. |
17BQ04 | ESPaDOnS | Sep 5 - 10 | 6 | Done | This ESPaDOnS run was very successful. Although thin cirrus affected some nights, we never stopped observing. |
17BQ05 | MegaCam | Sep 11-24 | 14 | Done | This was an excellent run for MegaCam, with only 16 hours lost to weather (mostly high humidity), and less than 1h lost to technical issues. |
17BQ06 | SITELLE | Sep 25-28 | 4 | Done | This short SITELLE run was successful. Only 1h was lost to a technical issue with the windscreen. Except for a couple of hours with thin cirrus, the sky was photometric. The Image Quality, however, was very poor on the last night (1.5 to 2 arcsec). |
17BQ07 | WIRCam | Sep 29 - Oct 9 | 11 | Done | The defective filter wheel parts that failed on Sep 5 were replaced and tested in time to mount WIRCam Sep 29. WIRCam replaced the ESPaDOnS run that was scheduled for Sep/Oct. Most nights were affected by either thin cirrus or thicker clouds; for 3 of 11 the nights, most of the time was lost to high extinction. With about half of the nights remaining for this semester, about half of the hours for A & B programs have been validated. |
17BQ08 | SITELLE | Oct 10-19 | 10 | Done | This was a challeging run, with clouds or high humidity affecting a few hours every night. The first night was also lost to a power outage. On the bright side, it is possible to reduce data taken over 2 or more nights, and piece together the observations. |
17BQ09 | MegaCam | Oct 20-26 | 7 | Done | This short MegaCam run was affected by bad weather, with 3.5 nights lost to high humidity, and a few hours of thin cirrus on other nights. |
17BQ10 | ESPaDOnS | Oct 27 - Nov 8 | 13 | Done | A very good ESPaDOnS run where we were able to focus on high priority programs and also get observations for quite a few overfill programs. |
17BQ11 | SITELLE | Nov 9-13 | 5 | Done | Despite the unfavorable forecast, this last SITELLE run of the semester went relatively well. One night was lost to weather, and clouds affected all other nights to various degrees. |
17BQ12 | MegaCam | Nov 14-27 | 14 | Done | This MegaCam run was challenged by high winds (almost 3 nights lost) and adverse weather conditions, like clouds, fog, and snow (almost 4 nights lost). The other 7 nights generally saw photometric skies with good Image Quality. |
17BQ13 | WIRCam | Nov 28 - Dec 7 | 10 | Done | This WIRCam run, especially the first 4 nights, was affected by bad weather or bad Image Quality. Only the very last night of the run had perfect conditions for observing. |
17BQ14 | MegaCam | Dec 8-25 | 17 | Done | The weather severly impacted the productivity of this winter run. MegaCam cooling also started to fail toward the end of the run. The exchange to ESPaDOnS was performed one day early. |
17BQ15 | ESPaDOnS | Dec 26 - Jan 9 | 16 | Done | This last run of semester 2017B was very successful. The weather started with variable clouds, precipitation, or high winds, but improved quickly. Only 15 hours were lost to weather. Only 2.5h hours were lost when a cable fell off and a network switch became unplugged. Half a night was used for engineering. Nine of the 14 A or B programs have obtained all their observations. The remaining programs have obtained between 80% and 95% of the requested observations. |
17BQ16 | MegaCam | Jan 10-24 | 15 | Done | This last MegaCam run of the semester was challenged by bad weather (60h lost) and cooling issues with the instrument (a total of 18h lost on 3 separate nights). |
17BQ17 | WIRCam | Jan 25-28 | 4 | Done | 2017B programs that would have been observed during the last 3 nights of January will be observed during the February WIRCam run. This short run was completely lost to bad weather (snow, ice, high humidity). |
17BQ18 | ESPaDOnS | Jan 29-31 | 3 | Started | 2018A ESPaDOnS programs will be started during this end-of-January run, and into February. |
