Spaceweather.com – Live Report – X-class Flare – 11 June 2014

What an active day, after a minor impulsive M-class flare from region 2080 the new region 2087 produced an M3 class solar flare, it was short in duration so we expect no associated CME with it. One hour later Active Region 2087 produced it’s third X-class flare, it was exactly X1.0. Unfortunately our alert system suffered from a minor bug and tweeted it as an M8 flare, we excuse us for that. The bug will be resolved later today.

Active Region 2087 looks to be in a phase of growth, it is still difficult to determine it’s magnetic complexity because it is still near the limb but from first sight there looks to be a delta structure within the region that’s strong enough to produce further flares.

Later today, when LASCO imagery is complete, we’ll take a look if there was a CME associated. Watch us for updates.

Spaceweather.com – Double X Flare – 11 June 2014

DOUBLE X-FLARE: Forecasters expected an X-flare on June 10th, and the sun complied. The source, however, was unexpected. A new sunspot (AR2087) suddenly emerging from behind the sun’s southeastern limb erupted twice, producing an X2.2-flare at 11:42 UT and an X1.5-flare at 12:52. This extreme ultraviolet image from the Solar Dynamics Observatory shows the first blast:

X-rays and UV radiation from the double flare created a wave of ionization in Earth’s upper atmosphere, altering the normal propagation of radio transmissions over Europe. Rob Stammes recorded the sudden ionospheric disturbance (SID) from his laboratory in Lofoton, Norway: data. Preliminary coronagraph images from NASA’s STEREO probes show a bright CME emerging from the blast site, traveling mostly away from the sun-Earth line. No strong impacts are expected.

Before today’s double-eruption, forecasters had been keeping a wary eye on sunspot complex AR2080/AR2085. Almost directly-facing Earth, those two sunspots have ‘delta-class’ magnetic fields that harbor energy for X-flares. The emergence of sunspot AR2087 on the southeastern limb adds another potent source to the mix. Solar activity is high, and likely to remain so in the days ahead. Solar flare alerts: text, voice

SpaceWeather.com – M7 Solar Flare Erupted on 18th – 18 April 2014

M7-CLASS SOLAR FLARE: Sunspot AR2036 erupted today, April 18th, at 1307 UT, producing a strong M7-class solar flare. NASA’s Solar Dynamics Observatory recorded the extreme ultraviolet flash:

First-look data arriving from NASA’s STEREO-Ahead spacecraft suggest that a CME is emerging from the blast site. If so, it probably has an Earth-directed component. Stay tuned for updates. Solar flare alerts: text, voice
