Angry Regions Are Here Again: Solar Storm Forecast 04-20-2017

The Sun shows its angry face again as two regions that sent us 7 big flares just two weeks ago rotate back into Earth view. They have already fired off one near M-class flare and launched a non-Earth-directed solar storm. Amateur radio operators should expect possible radio blackouts on the dayside of Earth this week. GPS/GNSS operators should also expect issues near the dawn-dusk terminators. We also have 2 coronal holes sending us fast wind and that means storm conditions are great for aurora! Catch the details, learn when the storms are expected, and see what else the Sun has in store this week.

None of this would be possible without the hard work and dedication of those who have provided all of this data for public use.

Images c/o NASA/ESA/CSA (most notably the superb SDO, SOHO, ACE, STEREO, CCMC, JPL & DSN teams, amazing professionals, hobbyists, institutions, organizations, agencies and amateurs such as those at the USAF/HAARP, NICT, NOAA, USGS, Environment Canada, Natural Resources Canada, Intellicast, Catatania, rice.edu, wisc.edu, sonoma.edu ucalgary.ca, rssi.ru, ohio-state.edu, solen.info, and more.
