Along with our usual round-up of papers on FRBs and related items this month, we note the passing of Sir Francis Graham-Smith [obituary], a pioneer of radio astronomy whose work on radio pulsars will be familiar to many community members. We also note that the FRB 2025 meeting is almost here! The deadline for late breaking news items is July 1st, in case you want to squeeze in your exciting new result.

• No persistent radio source was detected with the uGMRT at 1.26 GHz at the site of repeating FRB 20230607A (ATel 17230), down to luminosity limit 2x deeper than the persistent sources associated with FRBs 20121102A and 20190520B. The non-detection is especially interesting given the high rotation measure of the FRB (~12000 rad/m^2).
