Giant Coronal Hole CH521 in the sun’s upper atmosphere has just turned directly toward Earth. Coronal holes are places where the sun’s magnetic field opens up and allows the solar wind to escape. A stream of solar wind flowing from this particular gap is en route
Skywatchers in Australia were treated to unexpected beautiful views of the Aurora Australis. This timelapse is by Alex Cherney in Flinders Victroia, Australia who captured auroral views on June 19th 2012 in between clouds and rain. CME generated geomagnetic storming
The Kp index dropped below the Minor Geomagnetic Storm threshold (Kp=4). Minor storm flareups at high latitudes could still take place for the remainder of the day. Geomagnetic Storming continued during the day at very high latitudes as effects from an incoming CME
As expected, an interplanetary shock wave associated with the “double CME” of June 13-14 hit Earth’s magnetic field today around 09:57 UTC.ACE Spacecraft detected an incoming shock passage around 09:00 UTC this morning and a Geomagnetic Sudden Impulse was recorded by
A fast-moving CME that left the Sun on June 14th is expected to scoop up another CME already en route and deliver a double-blow to Earth’s magnetic field on June 16th. Weak-to-moderate geomagnetic storms are possible when the clouds arrive.A long duration solar
The Bz continues to tilt south and a minor G1 Geomagnetic Storm (Kp=5) is now in progress. Be on the lookout for Aurora at very high latitudes. The Bz Component of the Interplanetary Magnetic Field (IMF) is currently tipped south and this may help trigger Aurora at
Solar wind reached near 700 km/s and this helped stir up a brief G1 Level Geomagnetic Storm (Kp=5) at high latitudes during the early hours of Wednesday morning. Migratory animals are affected at this and higher levels and aurora is commonly visible at high
Earth has entered a high-speed solar wind stream, and this is causing geomagnetic activity at high latitudes. A minor Geomagnetic Storm (KP=5) is now in progress.The Solar Wind is currently around 600 km/s at this is helping stir up geomagnetic activity at high
An interplanetary shock wave possibly associated with the M5-class solar flare of May 17th swept past Earth on May 20th around 02:00 UTC according to SpaceWeather. The shock’s arrival caused geomagnetic activity around the poles, and several outbreaks of
This is the third day in a row that geomagnetic storms have circled the poles. A mild (Kp=5) geomagnetic storm is underway. It looks like it subsiding now. High-latitude sky watchers should be alert for auroras. The source of this activity is a high-speed solar wind
