Cosmic-solar radiation as the cause of earthquakes and volcanic eruptions

In the last a few decades research papers started to appear in the scientific press that clearly show correlation between cosmic-solar radiations and destructive geological events like earthquakes & volcanic eruptions. These research papers are supported by statisti

Strong (S3) solar radiation storm in progress (May 23, 2013)

Solar radiation storm reached S3 (Strong) levels at approximately 03:00 UTC on May 23, 2013. Strong solar radiation storm is still in progress due an M5.0 solar flare originating in departing Sunspot 1745 on the Sun's western limb. The M-class

G1 (Minor) Geomagnetic Storm in progress - May 18, 2013

G1 (Minor) Geomagnetic Storm conditions are now occurring due to the arrival of the CME from May 15, 2013. During G1 Geomagnetic Storm, weak power grid fluctuations can occur, minor impact on satellite operations is possible, aurora is commonly

Geomagnetic storms - basic terms, data, plots and graphs

A coronal mass ejection (CME) that erupted on March 15, 2013, hit Earth's magnetic field at 06:00 UTC on March 17, 2013. The solar wind speed reached 700 km/s and sparked a moderately strong G2 (Kp=6) geomagnetic storm and minor S1 solar radiation

Geomagnetic storming levels back to normal

Geomagnetic storming reached the G2 (Moderate) level at high latitudes again early today. Bright auroras could be seen around Arctic Circle. It was sparked by one of two coronal mass ejections observed on September 2.  Solar radiation storm levels have returned to

CME shock from solar filament on August 31 hit Earth, geomagnetic storming in progress

Solar filament eruption on August 31 generated at least two potentially Earth directed CME clouds. Earth was hit by first CME shock, observed in the solar wind around 11:20 UTC. The impact induced significant ground currents in northern Scandinavia and

mars curiosity hit by solar radiation storm

Mars rover Curiosity experienced and measured X2-class solar flare radiation storm

On January 27, 2012, Curiosity’s spacecraft was hit by the most intense solar radiation storm since 2005.  The event began when sunspot AR1402 produced an X2-class solar flare. (On the “Richter Scale of Solar Flares”, X-flares are the most powerful kind.)  The

Increased solar activity after strongest solar radiation storm since 2006

Growing Sunspot 1402 erupted in morning of January 23, 2012 around 04:00 UTC, producing a long-duration M8.7 solar flare. Each category for x-ray flares (B,C,M,X) has nine subdivisions ranging from  C1 to C9, M1 to M9, and X1 to X9. This one ranks M9, which is only

Radiation storm and CME heading toward Earth, geomagnetic storm and aurora events expected

A solar radiation storm is in progressaround Earth. At the moment, the storm is classified as minor, which means it has little effect on our planet other than to disturb HF radio transmissions at high latitudes. Bigger effects, however, may be in the offing. The

Solar radiation storm in progress

A solar radiation storm is in progress around Earth. At the moment, the storm is classified as minor, which means it has little effect on Earth other than to disturb HF radio transmissions at high latitudes. Energetic protons, which make up the bulk of the storm,

Whales are suffering skin damage as ultraviolet radiation increases

Many whales are now acutely sunburned, with cases escalating in recent years, according to new research.The study, published in the Proceedings of the Royal Society B, is the first to demonstrate that sun damage to whale skin is on the rise and is likely tied to

M2.5 solar flare, CME expected on June 9 and 10

On June 7th at 0641 UT, magnetic fields above sunspot complex 1226-1227 became unstable and erupted. The resulting blast produced an M2-class solar flare, an S1-class radiation storm, and an unbelievable movie:Much of the plasma thrown up by the blast simply fell
