62-509 2021-05-14 00:17 SoftToO Gaia21cha ALEe140144 - ALEe140147 Target observed in imaging mode with strong winds and poor seeing above 2.0 arcsec. The spectroscopic acquisition had been interrupted due to strong winds. Observed
62-509 2021-05-16 00:54 SoftToO Gaia21cha ALEe160145 - ALEe160149, ALEe160155 - ALEe160159, ALEe160160 - ALEe160163 Observed with clear skies, closed low hatch & side ports and 1.1-1.7 arcsec seeing. First exposure at ~4am interrupted by a readout due to guiding lost and clouds Observed
62-509 2021-05-28 00:30 SoftToO Gaia21clo ALEe280158 -ALEe280166 Clear sky, seeing under 1.5\" Observed
62-509 2021-06-02 00:44 SoftToO Gaia21cbx ALEf020125 - ALEf020129, ALEf020130 - ALEf020134 Clear skies, variable, but decent seeing. Observed
62-509 2021-06-15 00:47 SoftToO Gaia21crx ALEf150093 - ALEf150101 target observed with seeing above 1.0 arcsec . Clear skies but strong winds. Observed
62-509 2021-07-09 00:42 SoftToO Gaia21dde ALEg090121 - ALEg090129 Target observed with clear sky and seeing above 1.5arsec. 1st OB was the spectra and the 2nd the imaging. Observed
62-509 2021-07-29 00:40 SoftToO Gaia21cut, Gaia20cut ALEg290091 - ALEg290100 Clear sky with seeing 0.9 Observed
62-509 2021-09-06 00:41 SoftToO Gaia21dpz ALEi060464 - ALEi060473 Observed with a clear sky and seeing that ranged from 0.8 to 1.2 arcsec. During observations, wind speed was close to 15m/s and pointing was close to upwind. If standard star is required for the spectroscopic data, Feige_110 was observed on the same night as part of the 62-507 program and it has the same setup. Observed
62-509 2021-09-07 00:00 SoftToO Could not observe the targets because ALFOSC became unavailable that night. Failed
62-509 2021-09-09 00:38 SoftToO Gaia21ect ALEi090058 -ALEi090066 Clear skies, with excellent seeing around 0.6\". presence of Aerosols during the observations. Observed
62-509 2021-09-30 00:00 SoftToO None None Wind direction from SE-E in combination with high aerosol levels (~22µg/m3) due to the volcanic ashes, prevented us from opening the telescope. Failed

 

The above information is collected from the ToO/Mon reports that have been created by the observer.

Should any of the observations have been carried out using the OB system, you will find additional information HERE
