The magnetic storm decrease to a category G1 (minor) level on June 19th. Radio blackouts reached the R2 (moderate) levels on June 17th due to an energetic solar flare that erupted at 4:55 P.M.

Outlook For June 25-July 1

Space weather is expected to be at minor to moderate levels. An active sunspot region is due to return to the visible side of the sun on June 27th and may have the potential to produce radio blackouts. The geomagnetic field may reach category G1 and G2 during the period due to a number of recurring coronal hole and their associated high speed solar winds.
