R2 Conditions Reached on 03 June

R2 radio blackout conditions occurred on 03 June due to an isolated class M9.5 solar flare from Region 4455 near the center disk in the Sun's northern hemisphere. A particle event from this flare is unlikely given the source's location, but there is a slight chance (3%) of one late in the UTC on 03 June. As of 03:25 UTC, no associated eruptions have been seen in available coronagraph imagery, but this will continue to be assessed as new data comes in. A high chance for additional M-class (R1-R2) flare activity is expected to persist through 05 June.
