A sharp gust of solar wind hit Earth’s magnetic field

A sharp gust of solar wind hit Earth's magnetic field at approximately 20:30 UTC on June 4, 2011. High-latitude sky watchers in both hemispheres should be alert for auroras. Solar windspeed: 495.9 km/secdensity: 2.6 protons/cm3 Planetary K-indexNow: Kp= 5…

A solar wind stream is buffeting Earth’s magnetic field, sparking Southern Lights around the Antarctic Circle. Ian Stewart sends this picture to SpaceWeather.com from a jetty near Hobart, Tasmania:”Not long after sunset a friend rang to ask whether a faint arc of

Sun’s active region turns toward Earth – geomagnetic storm in progress

Sun’s active region turns toward Earth – geomagnetic storm in progress

The quiet sun is waking up. New sunspot 1226 emerging over the sun’s southeastern limb is crackling with strong C-class solar flares. So far none of the blasts has been geoeffective, but this could change in the days ahead as the active region turns toward

British Defence Secretary Liam Fox will next week attend a summit of scientists and security advisers who believe the infrastructure that underpins modern life in Western economies is potentially vulnerable to electromagnetic disruption.Blogger’s and scientists

Sundiving comet and coronal mass ejection

Sundiving comet and coronal mass ejection

A comet dove into the sun on May 11th and seemed to trigger a massive eruption. Watch the movie, then scroll down for further discussion.

A comet goes in; a CME comes out. Coincidence? Probably, yes, the sequence was coincidental. The comet disintegrated

Comet hit the Sun?

Comet hit the Sun?

A comet just discovered by amateur astronomer Sergey Shurpakov is diving past the sun today, and it will probably not survive. Click here to view a movie of the death plunge recorded by the Solar and Heliospheric Observatory–and check back for updates in the hours

Spectacular CME, active region approaching Earth

Spectacular CME, active region approaching Earth

A sunspot located just behind the sun’s eastern limb erupted during the waning hours of May 9th, hurling a spectacular coronal mass ejection into space: movie. NASA’s Solar Dynamics Observatory photographed hot magnetic loops towering over the edge of the sun in the

Subsiding geomagnetic storm (May 04, 2012)

Earth is exiting a solar wind stream that has been stirring up geomagnetic storms around Earth’s poles since April 29th. Over the past few nights, observers have seen auroras over the South Pole, Germany, Wisconsin andMichigan. The chances for more auroras are

Geomagnetic storm in progress

The geomagnetic field was unsettled to active at mid latitudes. Minor to major storm conditions occurred at high latitudes due to Coronal Hole (CH) high-speed stream (HSS) effects. Solar winds speeds were sustained above 620 km/s during the period. The greater than 2
