* These proposals have been accepted in the category of Intensive Program. S20B-088 will be assigned 7 nights also for S21A. S20B-097 will be assigned totally 200.9 hours from S20B to S23A.

In order to compensate surplus telescope times, which resulted from cancellations of engineering time influenced by COVID-19, five backup proposals (see *1 below) were newly accepted and supplemental nights were added to already accepted four proposals (see *2 below).
