An exploding meteor responsible for a huge bang at Niue island in Pacific

An exploding meteor is believed to be responsible for a huge bang that reverberated around the Pacific island nation of Niue last week.Niue police chief Mark Chenery said the loud bang on Wednesday night woke the island's 1200 residents and he initially thought a

M3.5 solar flare took place around Sunspot 1263

At 18:10 UTC Monday, a short duration M3.5 Solar Flare took place around Sunspot 1263. Because of its location, any explosions at this point may not be earth directed.Just when solar activity was slowing down, an M3.5 Solar Flare took place around Sunspot 1263

Behemoth sunspot 1263 has almost doubled in size

Behemoth sunspot 1263 has almost doubled in size this weekend. A 28-hour movie from NASA's Solar Dynamics Observatory shows the spot developing a tail that has added some 50,000 km of length to the active region.This development may increase the likelihood of a stro

One of the strongest geomagnetic storms in years subsiding

Earth's magnetic field is still reverberating from a CME strike on August 5th that sparked one of the strongest geomagnetic storms in years. Registering 8 on the 0 to 9 "K-index" scale of magnetic disturbances, the storm, at its maximum, sparked...

Geomagnetic storm still in progress but lingering

A geomagnetic storm is in progress. It began on August 5th around 18:00 UT when a CME struck Earth's magnetic field. At its peak during the hours just after impact, the storm registered 8 on the 0 to 9 "K-index" scale of geomagnetic disturbances,...

Strong solar activity - M9.3 solar flare took place, expecting CMEs

Sunspot 1261 is at it again, this time producing a strong M9.3 Solar Flare at 03:57 UTC Thursday morning. It also turns out that yet another Coronal Mass Ejection (CME) was produced and you can see it in the still image below captured by STEREO Ahead.Proton Levels are o

A moderate solar flare reaching M6.0 took place around Sunspot 1261

A Moderate Solar Flare reaching M6.0 took place around Sunspot 1261 at 13:47 UTC Wednesday and appears to be long in duration. A brief R2 Radio Blackout resulted. A bright Coronal Mass Ejection (CME) is associated and can be seen in the image below. It is most likely

Massive double Sunspot 1263 - wider than the Earth - harbors energy for powerful X-class solar flares!

Double sunspot 1263 is a whopper. Its two dark cores are each wider than Earth, and the entire region stretches more than 65,000 km from end to end. The clarity of  image is impressive. Note the granulation of the stellar surface surrounding the main dark cores.

M1.4 Earth-directed solar flare took place

Magnetic fields above sunspot 1261 erupted this morning at 0648 UT, producing an M1-class solar flare. The blast also hurled a bright coronal mass ejection toward Earth. This movie from the STEREO-Ahead spacecraft shows the cloud racing away from the sun at almost

Unbelievable events in Antarctica

We only believe what we see with our own eyes and then even then, if we do not want to see something, we will not see it even if it’s there. Lately, I have been taking virtual journeys down to the Antarctic Circle to the Neumayer Station, which has a 24/7...
