Sky was partly cloudy. It affected several observations.
At 8.21 we observed again LTT3864 with gr13 and gr16.
We attempted to observe the following targets but without success:
AT2020tk Clouds led the fail.
AT2020yk Not detected. Light curve consisted only of one data point. We wonder whether the transient is real.
