The CME was hurled in our direction yesterday by a “dark plasma explosion,” described below. Following close behind the CME,\u00a0a stream of high-speed solar wind<\/a>\u00a0could arrive on\u00a0Aug. 18th<\/strong>, boosting the odds of a geomagnetic storm on that date as well<\/p>\n\n\n\n

DARK PLASMA EXPLOSION ON THE SUN (UPDATED):\u00a0<\/strong>Yesterday, the sun hurled a plume of dark plasma into space following a dramatic explosion around sunspot AR3076. NASA’s Solar Dynamics Observatory recorded the blast, which began on Aug. 14th around 1130 UT:<\/p>\n\n\n\n

Traveling faster than 600 km\/s (1.3 million mph), the plume tore through the sun’s outer atmosphere, creating a coronal mass ejection (CME).\u00a0Newly updated images<\/a>\u00a0from the Solar and Heliospheric Observatory (SOHO) confirm that the CME has an Earth-directed component. It could sideswipe Earth’s magnetic field on Aug. 17th, producing\u00a0minor<\/a>\u00a0to\u00a0moderate<\/a>\u00a0geomagnetic storms<\/p>\n\n\n\n

Description: A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.<\/p>\n","protected":false},"excerpt":{"rendered":"
