A solar storm means northern lights may flare across nighttime skies across northern states, stretching from New York to Washington, on Monday, say federal space weather officials.
The moderate "G2" geomagnetic storm predicted for Monday was announced by the National Oceanic and Atmospheric Administration's Space Weather Prediction Center on Saturday. The storm springs from a solar outburst noted on Friday by NASA's Solar Dynamics Observatory (SDO).
"Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms," north of 55 degrees northern latitude, warns the advisory. Radio signals may also suffer in northern regions and spacecraft may be affected as well.
