X1.6 Flare on the Sun. Sunspot Straight Earth

Active region 2158 solar flare strength X1.6 directed towards Earth


The sun emitted a significant solar flare, peaking at 1:48 p.m. EDT on Sept. 10, 2014. NASA's Solar Dynamics Observatory captured images of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground.  However when intense enough they can disturb the atmosphere in the layer where GPS and communications signals travel.

Coronal Mass Ejection (CME) was generated and a part of it is headed toward our planet.

A Type II (velocity 3750 km/s) and Type IV radio emissions were associated with the event. Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections and solar radiation storms.

Additionally, a 10cm Radio Burst (tenflare) lasting 57 minutes with peak flux of 1300 sfu was associated with the event. 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.
