After the outburst of new observational results at the recent FRB2021 meeting, we bring you a slightly shorter newsletter this month. Of particular interest, however, is the reappearance of SGR 1935+2154 at high energies; we wait and hope for a Giga-Jansky radio burst! We also welcome special guest editor Jason Hessels who has helped us curate this month's list of new papers and results. As always, we hope our readers are staying safe and healthy wherever they are!
