Although there was a large S/F and CME from old Sunspot Region 1429 that contributed to the halo CME there was also a filament eruption from the NE limb immediatly after, followed by a C5.3 flare the 27th @02:50 UTC with an associated CME (seen on SDO) from Sunspot Region 1444. We can expect this latter CME to be geoeffective. NASA and NOAA are not mentioning or giving any calculations for it, but it was very evident on SDO. Since we have no plane of sky ejection data, a rough guess would be that we can expect to see it arrive somewhere between tonight around 11:00 EDT through tomorrow afternoon. [ link to sdo.gsfc.nasa.gov] [ link to sdo.gsfc.nasa.gov] [ link to sdo.gsfc.nasa.gov] [ link to sdo.gsfc.nasa.gov] It looks like they are predicting a storm right around 18:00 on NOAA's simulator too.

It is the large hump between Mercury and Earth on this image from Stereo A HI2. Earth and Mars are very close together right now, so that's why they are written on top of each other and are hard to distinguish between.  Howdy, Tom, great to see you post this morning.  CACTus recorded two Type III halo CMEs within 4 hours. Both were generally from the NE; one on 3/26 @ 2312z and the second @ 0412z on the 27th.
