Strong geomagnetic storm levels (G3) are expected during June 8-9. The storming is predicted due to a large coronal mass
ejection (CME) that followed a major solar flare which occurred earlier today. This storm may cause some or all effects on the
following: power system grids may require voltage corrections, false alarms may be triggered on protection devices, and high
“gas-in-oil” transformer readings may occur; spacecraft may experience surface charging, increased drag, and orientation
problems may need corrections; HF (high-frequency) radio propagation may be intermittent; intermittent low-frequency radio
navigation and satellite navigation problems may occur; and the aurora may be seen as low as 50 degrees.
