Solar wind parameters indicate the arrival of a slow-moving CME

Solar wind parameters over the past 12 hours indicated the arrival of a slow-moving Coronal Mass Ejection (CME), likely produced on April 10. A period of G1 - Minor storming began at 08:59 UTC on April 15. Another enhancement in parameters is expected on April 16...

Negative polarity CH HSS sparks G2 - Moderate geomagnetic storm

Earth is under the influence of negative polarity coronal hole high speed stream (CH HSS) over the past 24 hours, sparking G2 geomagnetic storming. The source is a polar connected coronal hole located in the Sun's southern hemisphere. Geomagnetic K-index of 5...

Negative polarity CH HSS sparks G1 - Minor geomagnetic storm and auroras in the lower 48

Earth is under the influence of a negative polarity coronal hole high speed stream, sparking G1 - Minor geomagnetic storm and auroras as low as Michigan and Wisconsin, U.S. Enhanced solar wind parameters were observed on March 13, 2021, due to co-rotating...

Negative polarity CH HSS sparks G2 - Moderate geomagnetic storm

Earth is under the influence of a negative polarity coronal hole high speed stream (CH HSS) on March 1, 2021, sparking G1 - Minor and G2 - Moderate geomagnetic storming. Solar wind speed started increasing late February 28, from 369 km/s at 22:00 UTC to 521 km/s at...

Unsettled geomagnetic field due to CH HSS influences

Solar wind parameters in 24 hours ending 12:30 UTC today were indicative of a slightly enhanced and disturbed interplanetary magnetic field (IMF) due to weak coronal hole high speed stream (CH HSS) influences. Total IMF strength was variable, but steadily increased...

Cosmic radiation intensifying as we enter another Solar Minimum

An increased activity of cosmic rays has been observed around the Arctic Circle by the neutron monitors during the last year. The same trend was also noted in an independent measurement project carried out by the and the students of Earth to Sky...

A timelapse of the late October solar activity

Awesome time-lapse video features show 15 days of solar action from October 14th to 30th, 2014, showing sunspot AR 2192, the largest sunspot of the last two solar cycles or more than two decades. During the transition time Sunspot 2192 produced six X-class and 37 M-clas

Increasing threat of strong solar flares, CME hit anticipated

Solar activity has been low in last 24 hours, however, that might change today and in the coming days. New Active Region 2051 (S10W44, Dac/beta-gamma-delta) is growing rapidly and is now harboring energy for X-class solar flares. Eruptions from this regio

Rising threat of solar eruptions as new active regions rotate into Earth view

Four new active regions were numbered in the past two days - 1895, 1896, 1897 and old Sunspot 1875 which was just numbered as 1899. Sunspot 1897 already produced a few C-class flares and grew in size and complexity. This active region could produce strong flares in

Video of New Year's Eve solar blast

An incredible swath of plasma erupted from the Sun on December 31st, 2012 over a four-hour period. NASA stated that a massive eruption on the surface of the Sun blasted out a wave of super-hot plasma so high that it could tower over 20 Earth. The length of the

2012 In Review - Solar activity & space weather

We are now in a period called Solar Cycle 24 which started on January 8, 2008 and it is the 24th solar cycle since 1755, when recording of solar sunspot activity began. The solar cycle is the periodic change in Sun's activity

Solar activity at start of December

With no strong flares this week, the sun's x-ray output has nearly flatlined. The solar activity is quiet and is expected to continue for another 24+ hours. NOAA forecasters estimate a mere 20% chance of M-class solar flares.C-Class flares continue to be detected

Eruptions this weekend could be Earth-directed as Sunspot 1339 turns toward our planet

Sunspot 1339 has quieted since Nov. 3rd when it unleashed an X2-class solar flare. Nevertheless, it still poses a threat for powerful eruptions. The behemoth sunspot has a "beta-gamma-delta" magnetic field that harbors energy for more X-flares. Eruptions this weekend

Highlights of The Electric Universe Theory

The "Electric Universe" is a hypothesis, a new way of interpreting scientific data in the light of new knowledge about plasma and electricity. In this interpretation, gravity plays a secondary role behind the far more powerful electric force, and electrified plasma in

Second big satellite set to resist re-entry burn-up, ROSAT to fall in October

There is more space junk headed our way next month. A defunct German space telescope called ROSAT is set to hit the planet at the end of October – and it even is more likely than UARS to cause injury or damage in populated areas.NASA calculates a 1-in-3200 chance

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
