This month saw the release of the long-anticipated first CHIME/FRB catalog, including 535 bursts from 492 unique sources. The huge new collection, along with other exciting results from researchers worldwide, is sure to provoke lots of discussion at the upcoming FRB2021 conference, and we encourage all our readers to sign up for the meeting soon if they haven't already. Meanwhile, we hope our readers continue to stay safe and healthy during these difficult times.

• The Zwicky Transient Facility (ZTF) observed the field of the repeating FRB 20200120E in M81 on 433 distinct nights in g- and r-bands, for a total of 1190 exposures of 30 sec each. No high-significance (> 5 sigma) source was detected in individual images, and upper limits are reported on nights that the FRB was observed to repeat with CHIME (ATel 14666).
• The newly discovered Galactic magnetar, SGR J1555.2-5402, has a detected pulsation period of 3.8611(1) s from X-ray observations by the NICER instrument (ATel 14674).
• The newly-refurbished Allen Telescope Array has been used to detect a bright double-peaked radio burst from the repeating FRB 20201124A, with nine dishes operating at 1.5 GHz. The estimated fluences for the two components are 120 Jy-ms and 45 Jy-ms (ATel 14676).
