#SOLAR #FLARE AND RADIO BLACKOUT: A new sunspot is emerging over the sun's SE limb. It announced itself on May 31st with a long-duration M4-class solar flare:

A pulse of extreme #ultraviolet #radiation ionized the top of #Earth's #atmosphere, causing a shortwave radio blackout over the Pacific Ocean almost perfectly centered over Hawaii. Mariners and ham radio operators may have noticed loss of signal below 30 MHz for as much as an hour after 2252 UT.

Designated AR3323, the #sunspot is now turning toward Earth, and it appears to be growing more complex. NOAA forecasters estimate a 40% chance of more M-flares on June 1st.
