Major Solar Storms To Strike Earth This Week As "Black Supermoon" Looms
Earth is about to be strobed by three streams of solar wind–each flowing from a hole the sun's atmosphere. NASA's Solar Dynamics Observatory photographed the gaseous spigots on July 29th:
These are "coronal holes"–places where the sun's magnetic field peels back and allows solar wind to escape. Coronal holes look dark in extreme ultraviolet images of the sun because glowing-hot plasma normally contained there is missing.
The first of the streams is expected to arrive on Aug 1st, followed by two more in rapid succession on Aug. 4th. Polar geomagnetic unrest and possibly some minor magnetic storms are possible on those dates.

A Crazy Black Supermoon Will Happen on July 31st
According to Farmer's Almanac, some people call the second moon in a single month a Black Moon—this is the definition that's used most often, and the one that applies to the full moon happening on July 31st. The term has also been used where no new moon occurs in a month, which only happens every 5 to 10 years in the month of February.
This particular moon on July 31st is called a Black Supermoon because it will be near its closest point to Earth.
