QrunID | Instrument | HST Dates | # Nights | Status | Run Summary |
---|---|---|---|---|---|
18BQ01 | SPIRou | Aug 1 - 5 | 5 | Done | |
18BQ02 | MegaCam | Aug 6 - 15 | 10 | Done | |
18BQ03 | ESPaDOnS | Aug 16 - 18 | 3 | Done | ESPaDOnS' spectrograph was damaged during an electrical storm on Aug 18; the night of Aug 18/19 was mostly lost to high humidity. The rest of the run has been cancelled for now. |
18BQ04 | WIRCam | Aug 19 - 20 | 2 | Done | |
18BQ05 | ESPaDOnS | Aug 21 - 29 | 8 | Done | ESPaDOnS' spectrograph was configured in the Star + Sky mode, and the camera focus was set at a reasonable position. Other Observing modes are not available at this time. Due to a technical issue with the top end handling ring, we were not able to mount WIRCam after the ESPaDOnS run. The exchange to MegaCam was performed one day early. |
18BQ06 | MegaCam | Aug 30 - Sep 13 | 15 | Done | This was a successful MegaCam run, with the equivalent of about 9 photometric nights, and sub arcsec Image Quality the majority of the time. The latter part of the run was affected by hurricane Olivia, which thankfully avoided the Big Island. |
18BQ07 | WIRCam | Sep 14 - 20 | 7 | Done | Almost 24 hours were lost to weather, but there were no technical issues. |
18BQ08 | SPIRou | Sep 21 - 25 | 5 | Done | The SPIRou technical commissionning continued. |
18BQ09 | SITELLE | Sep 26-27 | 2 | Done | Engineering related to the improvement of the Image Quality |
18BQ10 | ESPaDOnS | Sep 28 - Oct 1 | 4 | Done | This very short run was successful, despite extinction that was heavy at times. ESPaDOnS was repaired successfully after the August lightning strike. |
18BQ11 | SITELLE | Oct 2 - 11 | 10 | Done | This run was affected by high humidity and precipitation (about 3 full nights lost). The image quality was around 1" during observations. Progress has been made on a few programs. |
18BQ12 | MegaCam | Oct 12 - 15 | 4 | Done | This very short run was hampered by bad weather (about 2 and a half nights lost). |
18BQ13 | ESPaDOnS | Oct 16 - 23 | 8 | Done | ESPaDOnS is back into normal operations, and all 3 Observing Modes were available. The first snow of the season lightly dusted the summit on Oct 20/21. About half a night was lost to a communications issue with the summit, and a little over 3 nights were lost to high humidity. The priority was given to the top-ranked programs. |
18BQ14 | SPIRou | Oct 24 - 25 | 2 | Done | Both nights were mostly photometric, and allowed for an on-sky measurement of the (polarisation) cross-talk. |
18BQ15 | WIRCam | Oct 26 - Nov 1 | 7 | Done | This was a poor run for WIRCam, with only the last 1.5 nights with clear weather. |
18BQ16 | MegaCam | Nov 2 - 14 | 13 | Done | This was a relatively poor run, with only 3 solid nights of photometric skies. During all other nights, we were closed at some point because of high humidity or clouds. The total time lost to weather is almost 60h. |
18BQ17 | ESPaDOnS | Nov 15 - 19 | 5 | Done | This was a rather unproductive short run that was affected by bad weather. |
18BQ18 | WIRCam | Nov 20 - 28 | 9 | Done | This was a productive run, with only 7h lost to cloudy weather; 70% of hours in A-ranked programs have been validated, and 42% of hours for B-ranked programs have been validated. An additional short run might get scheduled in January. |
18BQ19 | SITELLE | Nov 29 - Dec 6 | 8 | Done | This was a very good run weather-wise, with only 4.5h lost to high humidity. We had about 5.5h lost to technical issues related to loss of modulation efficiency. |
18BQ20 | MegaCam | Dec 7 - 16 | 10 | Done | This was an excellent run with fewer than 5h lost to high extinction, and round 1.5h lost to technical issues. |
18BQ21 | SPIRou | Dec 17 - 19 | 3 | Done | |
18BQ22 | ESPaDOnS | Dec 20 - 27 | 8 | Done | This run started with excellent conditions (4 nights of clear skies and very good seeing) and ended in high humidity (last 4 nights). |
18BQ23 | MegaCam | Dec 28 - Jan 14 | 18 | Done | This was an excellent run, with much drier weather than what the summit of Maunakea has been experiencing over the past months. The Image Quality was also excellent. |
18BQ24 | SPIRou | Jan 15 - 17 | 3 | Done | |
18BQ25 | WIRCam | Jan 18-22 | 5 | Done | This short run was productive, thanks to the good weather (only 4h were lost to high humidity.) |
18BQ26 | ESPaDOnS | Jan 23-27 | 5 | Done | This short run was very productive, despite some time lost to weather (fog), and unusually high Image Quality during the last nights (seeing well above 1 arcsec, up to 2-3 arcsec!) |
18BQ27 | MegaCam | Jan 28 | 4 | Done |
