From Spaceweather:
SOLAR FLARES: Today, June 12th at 0055 UT, new sunspot 1081 unleashed an impulsive M1-class solar flare. NASA’s Solar Dynamics Observatory recorded the blast in high-resolution:
The explosion hurled a billion-ton coronal mass ejection (CME) off the sun’s western limb; the cloud will probably not hit Earth. The explosion also produced a Type II radio burst. “Although the Sun was setting here in New Mexico, I was able to record the burst at 28 MHz and 24 MHz,” says amateur radio astronomer Thomas Ashcraft. “Here is an audio file. The slow swoosh is radio noise from the sun!”
Thx will check it out.
We just had one in San Diego - at 8:09 PM PDT - felt like about a 4.5 or 5 - very short for the first couple of seconds and then just a really mild shaking for about 10-15 seconds. Abrupt at the beginning, and then VERY mild.
Wow, interesting. Thanks much.
