Solar Flare

Watch for aurorae!

From Space Weather: “ Big sunspot AR1429 has unleashed another major flare. This one is the strongest yet, an X5-class eruption on March 7th at 00:28 UT. NASA's Solar Dynamics Observatory recorded the extreme UV flash”

And: “A coronal mass ejection (CME) hit Earth's magnetic field on March 7th at approximately 0400 UT. The impact was not a strong one, but it could stir up polar geomagnetic storms anyway. High-latitude sky watchers should be alert for auroras.”
