SOLAR ACTIVITY: For the third day in a row, sunspot 1261 has unleashed a
significant M-class solar flare. The latest blast at 0357 UT on August 4th
registered M9.3 on the Richter Scale of Flares, almost crossing the
threshold into X-territory (X-flares are the most powerful kind). Also, at least
two coronal mass ejections are en route to Earth, and they could provoke mild
to moderate geomagnetic storms when they arrive on August 4th through 6th.
High-latitude sky watchers should be alert for auroras. Check
