GEOMAGNETIC STORM WATCH (G1): Over the past few days, a series of M-class solar flares may have hurled multiple CMEs toward Earth. In fact, so many CMEs have left the sun since Sept. 20th, analysts are having trouble sorting them out. Somewhere between two and four appear capable of grazing Earth’s magnetic field between Sept. 23rd and Sept. 25th. Minor G1-class geomagnetic storms are possible on all those days.

ANNULAR SOLAR ECLIPSE: Mark your calendar. On Oct. 14th–just one month from today–the Moon will pass in front of the sun, producing an annular solar eclipse visible from North and South America. Maps and observing tips @ Spaceweather.com.

NASA’s Solar Dynamics Observatory recorded a dramatic explosion near sunspot AR3425 during the late hours of Sept. 7th. Debris from the M2-category blast may be heading for Earth. NOAA analysts are currently unraveling several overlapping CMEs to determine which one, if any, might belong to this explosion.

A SIGNIFICANT EXPLOSION ON THE SUN: Giant sunspot AR3363 finally blew its top. An hours-long explosion on July 18th hurled a massive CME into space and triggered a radiation storm around Earth. The CME might graze our planet later this week. Full story @ Spaceweather.com.

CME IMPACT AND GEOMAGNETIC STORM: Arriving a full day earlier than expected, a CME hit Earth’s magnetic field on July 16th: data. The impact at 1920 UT caused a 20 nT jolt in the USGS’s magnetometer at Fredericksburg, Virginia, and a G1-class geomagnetic storm. More CME impacts are possible on July 17th and 18th due to multiple recent eruptions from big sunspot AR3363.

A VERY ACTIVE SUNSPOT: A new hyperactive sunspot is producing M-class solar flares every few hours. This is causing shortwave radio blackouts around all longitudes of our planet. If current trends continue, an X-flare could be in the offing. Full story @ Spaceweather.com.
