CME might deliver a glancing blow to Earth’s magnetic field on Jan. 7th

A magnetic filament in the sun’s northern hemisphere erupted on Jan. 5th and hurled a CME in the general direction of Earth. At first it appeared that the CME would sail north of Earth and completely miss our planet. However, analysts at the Goddard Space Weather Lab

Last night, NASA’s Solar Dynamics Observatory (SDO) observed an unusual event on the sun: An erupting cloud of plasma was eclipsed by a dark magnetic filament.The source of the explosion is a farside active region due to turn toward Earth in a few days. For now,

It’s one of the biggest things in the entire solar system. A dark filament of magnetism measuring more than 800,000 km from end to end is sprawled diagonally across the face of the sun. NASA’s Solar Dynamics Observatory took this ultraviolet picture of the structure

A pair of M-Class flares took place on Tuesday morning. The first one registered M1.2 and was centered around Sunspot 1348 which is located near the northwest limb. The second event at 12:43 UTC peaked at M1.9 and was located around Sunspot 1346 in the southern

There haven’t been any strong solar flares in days. Nevertheless, some impressive activity is underway on the sun. For one thing, an enormous wall of plasma is towering over the sun’s southeastern horizon. Huge solar filament is the biggest in a longer time period. A

The magnetic canopy of sunspot 1190 erupted on April 15th, producing an M-class solar flare (SDO movie). The brief blast did not, however, hurl a cloud of plasma toward Earth. NOAA forecasters estimate a 55% chance of more M-flares during the next 24 hours.

Newly-arriving data from NASA’s STEREO probes suggest that a coronal mass ejection (CME) might be heading toward Earth. The source of the cloud appears to be sunspot complex 1185-1186, which experienced an episode of magnetic instability during the early hours of April
