Space Weather News for August 5, 2011 http://spaceweather.com CME IMPACT: A coronal mass ejection (CME) hit Earth's magnetic field on August 5th around 1800 UT, setting the stage for possible geomagnetic storms on August 5th and 6th. Analysts at the Goddard Space Weather Lab report that the impact may have compressed Earth's magnetosphere enough to directly expose some satellites in geosynchronous orbit to solar wind plasma. High-latitude sky watchers should be alert for auroras after nightfall. Check http://space ...Continue Reading

Official Space Weather Advisory issued by NOAA Space Weather Prediction Center Boulder, Colorado, USA SPACE WEATHER ADVISORY BULLETIN #11- 1 2011 August 04 at 10:58 a.m. MDT (2011 August 04 1658 UTC) **** GEOMAGNETIC STORM EXPECTED **** Space Weather Bulletin August 4, 2011 NOAA Region 1261, very active over the past few days, produced the third of a sequence of Coronal Mass Ejections (CMEs) and Solar Radio Blackout Events early today. The net effect of that activity is convergent CMEs expected to ...Continue Reading

Space Weather News for August 4, 2011 http://spaceweather.com 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-lati ...Continue Reading

Space Weather News for August 3, 2011 http://spaceweather.com MINOR STORM WARNING: On August 2nd, the sun hurled a cloud of plasma (CME) toward Earth when magnetic fields above sunspot 1261 erupted. Analysts expect the CME to arrive during the early hours of August 5th, possibly sparking geomagnetic storms around the poles. This is not a big event; the eruption that propelled the cloud in our direction registered only "M1" (for medium) on the Richter Scale of Flares. Nevertheless, sky watchers at high lati ...Continue Reading
