CHANCE OF MINOR STORMS: NOAA forecasters say there is a chance of minor G1-class geomagnetic storms on Aug. 3rd when a high-speed stream of solar wind is expected to graze Earth’s magnetic field. The gaseous material is flowiing from a southern hole in the sun’s atmosphere
SOMETHING FLARE-Y THIS WAY COMES: Something just exploded behind the sun’s northeastern limb. On July 31st at 2309 UT, Earth-orbiting satellites registered a long-lastingC9.3-class solar flare; the intensity is probably an underestimate because it was partially eclipsed by the edge of the sun. NASA’s Solar Dynamics Observatory (SDO) saw hot debris flying away from the blast site:
Earth is not in the line of fire. The explosion is significant because it may herald an active region set to emerge over the sun’s northeastern limb later this week. A new sunspot group could bring an end to weeks of relative quiet
