We report a non-exhaustive list of times of X-ray flares from the magnetar candidate SGR 1935+2154 during its recent ongoing activity period, as detected by Swift/BAT with confident source identification, in order to facilitate targeted archival radio counterpart searches. We note that there are many more flares detected by BAT that are most likely from SGR 1935+2154, but originate from outside of the BAT imaging FOV so their origin cannot be definitively established. Those are not reported here.

This source continues to be actively flaring as of today (May 20 2020), and the last Swift/BAT imaging detection was on May 16 2020.

Many of the flare times reported below from the April 27-28 2020 period comprise parts of the 'burst forest' described in ATEL #13675.
