**** SPACE WEATHER OUTLOOK ****

Summary For June 15-21

- No G1 (Minor) geomagnetic storrming was observed during the period.
- No S1 or greater solar radiation storm events were observed during the period.
- Three R1 (Minor) events occurred: an M1.0 at 20/1500 UTC, an M2.6 at 21/0246
UTC, and an M1.3 at 20/0151 UTC. There was an isolated R2 (Moderate) event:an M6.8/2b flare at 21/1929 UTC.


Outlook For June 22-28

No G1 or greater geomagnetic storms are expected during the period, barring significant CME activity.
- Chances for an S1 or greater solar radiation storm event increase after 24 Jun due mainly to the increased magnetic complexity of Region 4473 as well as additional magnetically complex active regions  that are snticipated to return to the visible disk.
-Increasing chances for R1-R2 (Minor-Moderate) events are anticipated due primarily to the flare potential of Region 4473 combined with the expected return of old Region 4463.
