61-502 2021-05-08 01:18 SoftToO PG1323-086, Schwartz_2014B1, PonsBrooks,
2019U5, 2017K2
ALEe080105 - 121 Observed
61-502 2021-06-09 01:02 ToO Schwartz_2014B1, SA107_602, 2017K2,
2019U5, PonsBrooks
ALEf090093-5, 100-101,114-122 Observed
61-502 2021-06-26 00:28 SoftToO 2021L4, PG1525-071 ALEf260066 - ALEf260071 Observed with clear sky and seeing of around 1.4 arcsec for the science target and around 0.8 arcsec for the standard (even though they were observed in sequence) Observed
61-502 2021-06-27 00:28 SoftToO PG1525-071, 2021L4, 2021L4 ALEf270129 - ALEf270130, ALEf270131 - ALEf270134, ALEf270191 - ALEf270194 Dark and clear sky. The standard star was observed with a seeing around 1.2arcsec, but at UT ~22 a wave of bad seeing crossed the mountain so we retried the obs with a better seeing at UT ~23. The moon was still low down. Observed
61-502 2021-07-10 00:56 SoftToO PG2336+004, 2005QN173 ALEg100173 - ALEg100183 Target observed at the end of the night when the asteroid reached the maximum altitude. Dusty night with seeing generally around 1.0\" and no clouds. FJGG & AK Observed
61-502 2021-07-31 01:04 ToO Schwartz_2014B1, SA107_602, PonsBrooks,
2019U5, 2017K2
ALEg310046 - ALEg310048, ALEg310049 - ALEg310050, ALEg310143 - ALEg310145, ALEg310146 - ALEg310148, ALEg310146 - ALEg310148 Clear sky and good seeing. Observed
61-502 2021-09-09 00:16 SoftToO 2005QN173, SA92_249 ALEi090108 - ALEi090112 Targets observed with clear skies and good seeing around 0.6-0.8\". Observed
61-502 2021-09-11 00:20 SoftToO SA92_249 ,2005QN173 ALEi110073 - ALEi110074,ALEi110081 - ALEi110083 Note that the fault report with ID 3840 has most likely influenced the observations. Thus, the data quality might poor. Observed
61-502 2021-09-15 00:18 SoftToO 2005QN173, PG2336+004 ALEi150031 - ALEi150035 targets observed with good seeing, fluctuating around 1.0 arcsec. Presence of thin clouds during the observations. Observed
61-502 2021-09-19 00:26 SoftToO 2005QN173, PG2336+004 ALEi190071 - ALEi190073, ALEi190074 - ALEi190075 The targets have been observed with seeing that was fluctuating between 1 to 1.7arcsec. Observed
61-502 2021-09-29 00:00 SoftToO Bad weather condition during all the night. Failed
61-502 2021-09-30 00:00 SoftToO None None The targets have not been observed due to weather conditions (high volcanic ash risk). High dust distribution (>20µg/m3) during the whole night in combination with the SE-E wind direction prevented us from opening the telescope. Failed

 

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