April's solar flares through the eyes of Solar Dynamics Observatory

After 8 months without any significant solar flare, the Sun awakened on April 1, 2017, and unleashed 7 M-class solar flares over the next 2 days. The source of all of them was departing Region 2644. The series started with M4.4 on April 1 and was followed by M5.3,...

X-Class: A Guide to Solar Flares

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)

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

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

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

 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

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

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

A sharp gust of solar wind hit Earth's magnetic field at approximately 20:30 UTC on June 4, 2011. High-latitude sky watchers in both hemispheres should be alert for auroras. Solar windspeed: 495.9 km/secdensity: 2.6 protons/cm3 Planetary K-indexNow: Kp= 5...
