=====
The X1.4 flare of yesterday evening triggered an Earth-directed coronal mass ejection that will reach the Earth on July 14 around noon, with an uncertainty of many hours. Strong geomagnetic disturbances can be expected. Auroras might be visible in the hours following the arrival for observers with local night time and clear skies.

EARTH-DIRECTED X-FLARE: Big sunspot AR1520 erupted on July 12th around 16:53 UT, producing an X-class solar flare and hurling a CME directly toward Earth. Forecasters expect the cloud to arrive on July 14th. Its impact could spark moderate to severe geomagnetic storms, allowing auroras to be seen at lower latitudes than usual.

X-FLARE! Big sunspot AR1520 unleashed an X1.4-class solar flare on July 12th at 1653 UT. Because the sunspot was directly facing Earth at the time of the blast, this is a geoeffective event. Stay tuned for updates about possible CMEs and radio blackouts. Solar flare alerts: text, voice.
NASA's Solar Dynamics Observatory recorded a flash of extreme ultraviolet radiation from the blast site:
The UV and X-ray pulse from the flare will have partially ionized Earth's upper atmosphere on the dayside of our planet, disturbing the normal propagation of radio signals. Watch the Realtime Space Weather Gallery for possible reports of sudden ionospheric disturbances and other effects.
Watch the radial velocity animation at this link: http://www.solarham.net/ (its the bottom animation). It looks like the Sun is blowing a smoke ring at the earth! Torus shapes have special energetic properties.

The silence is broken! A major and long duration eruption reaching X1.4 around Sunspot 1520 peaked at 16:52 UTC Thursday afternoon. Type II and IV Sweep Frequency Events were recorded. This event was also responsible for a Strong R3 Radio Blackout on the sunlit side of Earth. A bright Coronal Mass Ejection was produced and appears to be Earth directed.
