    GEOMAGNETIC STORM WATCH (G3-CLASS): Strong G3-class geomagnetic storms are possible during the early UT hours of March 31st when a Cannibal CME is expected to hit Earth's magnetic field. During such storms, naked-eye auroras can descend into the USA as far south as, e.g., Illinois and Oregon (geomagnetic latitude 50o). North Americans should be alert for auroras after local nightfall on March 30th. The hours before dawn on March 31st are probably best for Europeans. Aurora alerts: SMS Text. X-CLASS SOLAR FLARE: Earth-orbiting satellites have just detected an X1.3-class solar flare (March 30 @ 1737 UT). The source is active...

    Solar storm heading towards Earth threatening to break your Sky TV and mobile phones (by Fri 09/30) http://www.express.co.uk/news/science/715472/Solar-storm-Earth-break-Sky-TV-mobile-phones SCIENCE A HUGE solar storm is heading towards Earth which could leave us without mobile phones, satellite TV and even electricity. By Sean Martin 17:53, Wed, Sept 2016 A solar storm is heading towards Earth Modern-day Britain could go into meltdown after scientists forecast the solar storm to hit between now and Friday which could wreak havoc with technology. Solar storms affect Earth’s technology as radiation is thrown at the planet from the Sun. While humans are protected from the radiation by...

    WASHINGTON: An unusual solar flare observed by a NASA space observatory on Tuesday could cause some disruptions to satellite communications and power on Earth over the next day or so, officials said. The potent blast from the Sun unleashed a firestorm of radiation on a level not witnessed since 2006, and will likely lead to moderate geomagnetic storm activity by Wednesday, according to the National Weather Service. “This one was rather dramatic,” said Bill Murtagh, program coordinator at the NWS’s Space Weather Prediction Center, describing the M-2 (medium-sized) solar flare that peaked at 1:41 am Eastern time in the United...

    Twin NASA spacecraft have provided scientists with their first view of the speed, trajectory, and three-dimensional shape of powerful explosions from the sun known as coronal mass ejections, or CMEs. This new capability will dramatically enhance scientists' ability to predict if and how these solar tsunamis could affect Earth. When directed toward our planet, these ejections can be breathtakingly beautiful and yet potentially cause damaging effects worldwide. The brightly colored phenomena known as auroras -- more commonly called Northern or Southern Lights -- are examples of Earth's upper atmosphere harmlessly being disturbed by a CME. However, ejections can produce a...

Dwarfed by the Sun's disk, the group of sunspots which make up region 30 actually cover an enormous area -- nearly 10 times the size of Earth. The panels above were recorded July 15,...

Meanwhile, the Sun itself has not been just sinking quietly below the horizon. For example on May 2nd, two enormous clouds of energetic particles blasted away from the...
