Sunspot 1513 unleashed second M-class solar flare - waves of ionization over Europe

Another M-class solar flare was released from Sunspot 1513 on Friday morning, the same sunspot that produced yesterdays M2.4 solar flare. The latest event measured moderate M2.2 and took place at 09:20 UTC Friday morning, June 29, 2012.Sunspots 1512 and 1513 have

Sunspot 1513 released M2.4 solar flare

Solar activity is now at moderate levels with a short duration M2.4 Solar Flare around Sunspot 1513 located in the northeast quadrant on June 28. This region continues to show signs of growth. No Earth-directed coronal mass ejections was released. There is R1 Radio

Double CME targets Earth

A fast-moving CME that left the Sun on June 14th is expected to scoop up another CME already en route and deliver a double-blow to Earth's magnetic field on June 16th. Weak-to-moderate geomagnetic storms are possible when the clouds arrive.A long duration solar

Another long duration solar flare erupted from Sunspot 1504 - M1.9

Another long duration, moderate, M1.9 solar flare  erupted from Sunspot 1504 on June 14, 2012. A 10cm Radio Burst (TenFlare) was recorded measuring 1400sfu and lasted for 103 minutes. The plasma cloud generated looks to be Earth directed and may impact Earth by

NASA's Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the Sun

Solar eruptions are on the rise as the Sun progresses toward the peak of its roughly 11-year-long activity cycle, now expected in mid-2013. Sun produced powerful solar flare rated as X5.4  (based on the peak intensity of its X-rays) on March 7, 2012. During a

Powerful solar tsunami along with yesterdays impulsive M3-Class solar flare

New sunspot 1496 unleashed an impulsive M3-Class solar flare on June 3rd at 17:55 UTC. The explosion hurled a coronal mass ejection (CME) into space. The cloud does not appear to be heading for Earth, although this conclusion could be revised by further analysis.
