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

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

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

Wonderful weekend auroras for start of May

Wonderful weekend auroras for start of May

It has been a good weekend for northern sky watchers. A solar wind stream hit Earth’s magnetic field on Saturday, sparking two days of auroras around the Arctic Circle. In Alberta, Canada, this morning, the month of May began with a psychedelic sky:High-latitude

A solar wind stream hit Earth’s magnetic field during the early hours of April 30th, sparking a high-latitude geomagnetic storm (slowly subsiding). In the United States, auroras descended as far south as Marquette, Michigan, where Shawn Malone took this picture before

A geomagnetic storm that sparked auroras around the Arctic Circle and sent Northern Lights spilling over the Canadian border into the United States on April 12th is subsiding. At the height of the display, Shawn Malone took this picture from the shores of Lake

Geomagnetic storm in progress (April 6, 2011)

The solar wind is blowing past earth at elevated levels today and combined with a south tilting Bz, is stirring up geomagnetic storming at high latitudes. C-Class flare activity is now taking place towards the new sunspot regions just to the east of Sunspot 1185. Keep

Earth is entering a stream of solar wind

Earth is entering a stream of solar wind

Earth is entering a stream of solar wind blowing ~500 km/s, and the encounter is stirring up geomagnetic activity around the Arctic Circle. The solar wind data (velocity and proton density) presented on spaceweather.com are updated every 10 minutes. They are derived
