A Powerful solar flare reaching M5.9 erupted from eastern limb. (pic is on comments bar) A moderately strong M5.9 solar flare was surprisingly just observed around region 2151 located in the southeast quadrant. Based on imagery, it also appears to be eruptive. More updates to follow regarding a possible coronal mass ejection (CME). Imagery courtesy of NASA Solar Dynamics Observatory (Little SDO) and GOES-15 Solar X-Ray Imager. ALERT: Type II Radio Emission Begin Time: 2014 Aug 24 1214 UTC Estimated Velocity: 593 km/s Description: Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event. SUMMARY: 10cm Radio Burst Begin Time: 2014 Aug 24 1209 UTC Maximum Time: 2014 Aug 24 1210 UTC End Time: 2014 Aug 24 1216 UTC Duration: 7 minutes Peak Flux: 409 sfu Latest Penticton Noon Flux: 132 sfu 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. 08/24/2014 @ 12:44 UTC A large release of plasma was observed in SDO/AIA 304 imagery. A coronal mass ejection (CME) is very likely. Because of the location of this event near the east limb, it will likely be directed mostly away from Earth. More updates regarding a possible Earth directed component to follow once updated coronagraph imagery is available.
