Greetings from the north-east corner of North America, where spring is in the air for both your editors. We are looking forward to a round of conferences this summer, including the upcoming AAS meeting in Pasadena, California and the IAU General Assembly (and FRB 2022) in Busan, South Korea, as travel slowly picks up again. Meanwhile, here is a quick round-up of the latest preprints and FRB-related papers.

IAU GA 2022: The IAU General Assembly in Busan, South Korea is coming soon, with the symposium on Fast Radio Bursts scheduled for 2-4 August 2022. We note that there have been visa problems for some scientists due to South Korea's COVID-19 policies, but that new policies regarding short term visas are coming into effect on June 1st. Please check with the organizers and your local South Korean embassy as you make your travel plans.

The National Radio Astronomy Observatory (NRAO) Users Committee is meeting in late July with a goal of providing community input to the NRAO management about current and future facilities. If you have any FRB-related comments you would like to be raised at this meeting, please contact Duncan Lorimer.

Do you have an item for future newsletters? Please send these via email to the editors (Emily and Shami) to be included in an upcoming issue.
