Glancing blow from this CME on Sunday? A glancing blow late on Sunday, by the CME from the M3.4 flare today. Minor to moderate (G1 to G2) is possible.

AR14104 produces it's first M-class an M1.6 at 0530, 1839 UTC. This area didn't exist a couple of days ago.... #Sun #Spaceweather

AR14100 lets loose an M8.2 to start the new day with a bang the solar flare was at 0531, 0006 UTC. There is a large associated CME that has to be Earth directed. #Sun #CME #Spaceweather

AR14100 continues it's output of M-Class solar flares with 2 more solar flares both had associated CME's, an M4.5 at 0531, 0818, and then an M2.9 at 0531, 1547 UTC. this particular flare was long duration and the CME appears to be quite large. Looks like we are going to see a

Here is the Cactus prediction models, please note the variable CME speeds for the CME that was associated with AR14100 M8.2 solar flare. This is a big one folks, and it's not on a glancing blow trajectory this one will nail us dead on, there may be some disruptions but nothing
