expected to be light to moderate, there is a weak 27 day recurrent
elevated solar wind pattern for 02-Jun and 04-Jun. G0 geomagnetic
conditions are expected, with a slight chance of an isolated G1
period. HF communications are expected to be normal to mildly degraded
during local night hours. Maximum usable frequencies (MUFs) are
expected to be near predicted values. Shortwave fadeouts are
