X-Class: A Guide to Solar Flares

November 21, 2012

Solar flares happen when the powerful magnetic fields in and around the Sun reconnect. They're usually associated with active regions, often seen as sun spots, where the magnetic fields are strongest. Flares are classified according to their strength. The smallest ones

G1 geomagnetic storm in progress (Video)

November 01, 2011

Solar activity picking up: sunspot is emerging over the sun's NE limb. Yesterday it unleashed three M-class solar flares and hurled a coronal mass ejections into space. Geoeffective solar activity could increase in the days ahead as the sun's rotation turns the sunspot

The “End” of the Mayan calendar, Solar Flares and Earth Changes

October 06, 2011

We have now celebrated the Cosmic Convergence and there is less than one night and one day before the fulfillment of the evolutionary plan for all of creation (or at least the attainment of the top level). As predicted the Ninth wave of this plan, which is coming to a

Expected impact of an incoming solar wind stream

August 29, 2011

NOAA forecasters estimate a 25% chance of polar geomagnetic activity today in response to the expected impact of an incoming solar wind stream.Solar activity is at very low levels and there is currently no chance for strong solar flares on the earth facing side of

Coronal hole in the sun's atmosphere is spewing solar wind toward Earth

August 26, 2011

A yawning dark hole in the sun's atmosphere is spewing solar wind toward Earth. NASA's Solar Dynamics Observatory photographed the opening during the early hours of Aug. 26th: Solar wind flowing from this coronal hole is expected to arrive on Aug. 28-29,

Solar wind hit Earth's magnetic field

June 17, 2011

A sharp gust of today, June 17th, at approximately 0230 UT. This probably signaled the arrival of a CME, en route from the sun since June 14th.

New insights on how solar minimums affect Earth

June 15, 2011

Since 1611, humans have recorded the comings and goings of black spots on the sun. The number of these sunspots waxes and wanes over approximately an 11-year cycle - more sunspots generally mean more activity and eruptions on the sun and vice versa. The number of

A sharp gust of solar wind hit Earth's magnetic field
