Double eruption on Sun

Double eruption on Sun

On October 1st around 10:17 UT, widely-spaced sunspots 1302 and 1305 erupted in quick succession, revealing a long-distance entanglement which was not obvious before. NASA’s Solar Dynamics Observatory (SDO) recorded the movie of the double blast:Since it was

Sundiving comet

Sundiving comet

A comet is diving into the sun today. Discovered on Sept. 29th by a group of four independent comet hunters (M. Kusiak, S. Liwo, B. Zhou and Z. Xu), the icy visitor from the outer solar system is evaporating furiously as it approaches the hot star. SOHO (the Solar and

Solar wind blasts Mercury

Solar wind blasts Mercury

At a NASA teleconference yesterday, researchers working with data from the Messenger spacecraft offered new evidence that gusts of solar wind are penetrating Mercury’s magnetic field and eroding material off the planet’s surface. The spacecraft has actually flown

Aurora reverberations

Aurora reverberations

A CME hit Earth’s magnetic field on Sept. 26th, sparking one of the strongest magnetic storms in years. At the peak of the Kp=8 disturbance, auroras were sighted around both poles and more than half a dozen US states. Magnetic reverberations continued for more than 48

Minor geomagnetic storm in progress

Minor geomagnetic storm in progress

A minor geomagnetic storm erupted earlier today, Sept. 28th, causing beautiful Wednesday-morning auroras in Canada and some northern-tier US states. These are, essentially, aftershocks of the severe storm on Sept. 26th. More reverberations are possible tonight.

Severe geomagnetic storm subsiding

Severe geomagnetic storm subsiding

A severe geomagnetic storm (Kp=7 to 8) that began yesterday when a CME hit Earth's magnetic field is subsiding.At the peak of the disturbance, auroras were sighted around both poles and in more than six US states including Michigan, New York, South Dakota, Maine, Ma

Strong solar activity causing severe geomagnetic storm

Strong solar activity causing severe geomagnetic storm

High-latitude sky watchers should be alert for auroras. A strong (Kp=7) geomagnetic storm is in progress. Earth's magnetic field has been strongly disturbed since approximately 1300 UT on Sept. 26th when a CME hit our planet. The impact strongly compressed the…

X1.9 solar flare took place

X1.9 solar flare took place

Sunspot 1302 is back at it again, this time producing an X1.9 Solar Flare at 09:40 UTC. This major event resulted in an R3 level radio blackout as well as producing a 10.7cm Radio Burst (TenFlare). A fast moving type II sweep frequency event is reported also. As this

Long duration X1.4 solar flare took place at new sunspot

Long duration X1.4 solar flare took place at new sunspot

Earth-orbiting satellites have detected a long-duration X1.4-class solar fare coming from a new sunspot on the sun’s eastern limb. The blast, which peaked at 1100 UT, produced a significant CME, but the cloud is not Earth-directed.
