We currently have a M1.9 LDE (long duration event) solar flare in progress. This flare came from sunspot region 1504 and peaked at a M1.9 at 14:30 UTC Thursday June 14, 2012. LED flares commonly occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections. Looking at the current STEREO A images, we can see there was indeed a CME produced in association with today's M1.9 LDE flare (images added below). Sunspot region 1504 is in a direct Earth facing position and because of this, the CME we see associated with this event is most likely Earth directed. There are currently no SWPC alerts or warnings issued for this event.
Today's M flare comes on the heals of a LDE M flare & Earth directed CME we saw yesterday June 13, 2012. This makes for 2 LDE M flares and 2 Earth directed CME's in around a 24hr period. We will add a update with the ETA of the CME from June 13th as well as the CME from today, June 14th.
This LDE flare vent is still in progress.Check back often for updates.
All updates will be added below.

Here we can see the CME produced with today's M1.9 LDE Solar Flare. Earth is located to the left hand side.
ANOTHER CME: On June 14th, for the second day in a row, sunspot AR1504 erupted and hurled a CME toward Earth. The fast-moving (1360 km/s) cloud is expected to hit our planet's magnetic field on June 16th at 14:00 UT, possibly sparking a geomagnetic storm. High-latitude sky watchers should be alert for auroras.credit: Spaceweather.com

INCOMING CMES: On June 14th, for the second day in a row, sunspot AR1504 erupted and hurled a CME toward Earth. The fast-moving (1360 km/s) cloud is expected to sweep up a previous CME and deliver a combined blow to Earth's magnetic field on June 16th around 10:16 UT. This animation shows the likely progression of the approaching storm:
According to the forecast track prepared by analysts at the Goddard Space Weather Lab, the CMEs will also hit Venus on June 15th and Mars on June 19th. Because Venus and Mars do not have global magnetic fields to protect them, both of those planets will probably lose tiny amounts of atmosphere when the CMEs strike.
