Science apparently marches on, even during a global pandemic. We hope you are staying safe and healthy, and offer you this brief round-up of this month's FRB news.

As of March 2020 the Transient Name Server (TNS) serves as the official name server and hub for distribution of FRB events. At the request of the FRB community, the TNS now operates two engines for designation of names, the original 'YYYYabc' (currently serving AT/SN), and now also 'YYYYMMDDabc' for FRBs. New pages and processes have been deployed, enabling the reporting, distribution and querying of FRB events using both interactive forms and APIs. Read more in the TNS AstroNote.
