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
