Double Shot CME's Have Arrived - June 16, 2012
The CME that occurred on June 13th and the CME from June 14th have merged in space en route to Earth and we are now seeing the front of the CME's arrive at Earths magnetosphere.
The density is slowly rising over the recent hours. We believe the main mass of the CME's has not yet hit. We come to this conclusion because of the merging in space of the 2 CMEs, the 1st CME was only a glancing blow, thus the front of the impact would be to the side.
The 2nd CME was a direct shot, thus the middle part of the impact would be more of a direct hit. We should see the results of this in the coming hours. A high latitude aurora watch is in effect for the evening of June 16, 2012. Auroras possibly visible as low as Michigan, New York, Wisconsin, Washington and Main.

M1.9 LDE Flare In Progress - June 14, 2012
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.
CME as seen on STEREO A @ 15:24 UTC |
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.

M1.2 LDE Solar Flare + Earth Directed CME - June 13, 2012
Updated @ 19:05 UTC June 13, 2012:
June 13, 2012 at 13:10 UTC Earth facing sunspot region 1504 produced a M1.2 LDE (long duration event) solar flare lasting for around 2hrs. Region 1504 is located in the southern hemisphere of the solar disk and has rotated into a direct Earth facing position. Because of the location of suns 1504, any CME produced by this region would be Earth directed. By looking at STEREO A and B, we can now see that there was a CME (coronal mass ejection) produced in association with today's M1.2 flare.
Check back often for updates for this event.
All updated info will be added below.
Here we can see the size and direction of today's CME as seen on STEREO A. Remember, with STEREO A, Earth is located to the left hand side.
