Summary For May 27-June 2

Space weather was at minor levels during most of the period. Isolated
category R1 (minor) radio blackouts occurred during most days due to
moderate-sized solar flares. Category G1 (minor) geomagnetic storm
conditions occurred on May 27 due to high solar wind velocities
associated with a coronal hole. There were no solar radiation storms.
For a list of adverse system effects caused by space weather storms,
