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.

To the left, we see a proton spike as recorded on the ACE Dynamic Plots.

Space Weather Message Code: SUM10R
Serial Number: 543
Issue Time: 2012 Jun 13 1416 UTC
SUMMARY: 10cm Radio Burst
Begin Time: 2012 Jun 13 1332 UTC
Maximum Time: 2012 Jun 13 1343 UTC
End Time: 2012 Jun 13 1347 UTC
Duration: 15 minutes
Peak Flux: 260 sfu
Latest Penticton Noon Flux: 141 sfu
Description: 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.


Space Weather Message Code: ALTTP4
Serial Number: 374
Issue Time: 2012 Jun 13 1416 UTC
ALERT: Type IV Radio Emission
Begin Time: 2012 Jun 13 1325 UTC
Description: 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

CME TARGETS VENUS, EARTH MARS: Active sunspot AR1504 erupted on June 13th at 1319 UT, producing a long-duration M1-flare and hurling a CME into space. According to analysts at the Goddard Space Weather Lab, the cloud will deliver a glancing blow to three planets: Venus on June 15th, Earth on June 16th, and Mars on June 19th. This animation shows the likely progression of the cloud:


  1. As those spots get larger and face us I predict an X 5 or greater flare from 1504


  2. That's only if they maintain there present growing complexity of their polarities,the Regions coming over the limb of the disc look very active and 'bright' on the SDO images : )

    I think one is the return of 1429..the Beast!

    Thank You NiNz and IWTB,TAG for your work..'Cesium.

  3. Opssy!

    Wrong Article,that was meant for the Top Article : )
