SOLAR WIND UPDATE: Earth is exiting a solar wind stream that sparked bright high-latitude auroras during the first week of March. Another stream is on the way. Flowing from a Southern hole in the sun's atmosphere, the gaseous material is expected to reach Earth on March 13th.

NEW SUNSPOT CRACKLING WITH FLARES: A New sunspot emerging over the sun's northeastern limb produced a C1-class solar flare yesterday March 9th.

A pulse of radiation from the flare briefly ionized the top of Earth's atmosphere, causing a low-frequency radio brownout over the Atlantic Ocean. Mariners and ham radio operators might have noticed unusual propagation below 10 MHz around 1235 UTC?

C-flares are relatively minor events. The potential of this sunspot for more intense flares is unknown. We'll find out more as it rotates into better view later!
