It has been a busy month in the FRB world, as multiple highly-active repeating sources are being followed up by different groups and telescopes - see our section on ATels below. We also draw your attention to a nice historical overview of the discovery of millisecond pulsars, just over four decades ago. We hope you enjoy this issue of the FRB Newsletter!

History

• The Discovery of Millisecond Pulsars: Don Backer and the Response to the Unexpected; Demorest & Goss; arXiv: 2407.18194

• The highly active repeating source FRB 20240209A (as reported in last month's Newsletter) has now been localized with the first of the CHIME outriggers (ATel 16682; correction in ATel 16687), leading to the identification of a host galaxy at redshift z~0.14 (ATel 16686). The Northern Cross also detected a burst from this source at 408 MHz (ATel 16692), and VLA observations show a compact radio source associated with the host galaxy (although not necessarily with the FRB source; ATel 16701).
• A repeating FRB 20240619D has been detected at MeerKAT, with three bursts in 2 minutes at 1.4 GHz (ATel 16690). A bright burst from the same source was also detected with Westerbork at 1.3 GHz (ATel 16732).
• There is a claimed compact radio continuum source associated with FRB 20240114A in MeerKAT imaging, although the source appears offset from the EVN-determined position (ATel 16695).
• Finally, the CHIME/FRB collaboration reported the discovery of yet another repeating source, FRB 20240316A, that appears to be in a heightened activity phase (ATel 16734; addendum ATel 16737). We look forward to hearing more about this source in future weeks.

• Another reminder: Registration and abstract submission is now open for the FRB 2024 conference in Thailand 4-8 November 2024. Early bird registration closes 30 July 2024, and abstract submission closes 30 August 2024.
• The annual Scintillometry conference will be hosted at the University of Central Florida from Monday October 28 to Friday November 1 2024. More details and registration information will come in the future.
