Flare and CME producing sunspot region 1429 - continues to grow and now has beta-gamma-delta configuration of its photospheric magnetic field.
Another major X-class flare from this active region is possible, most probably not earlier than tomorrow. As a result of region 1429 approach to the solar central meridian, another Earth-directed CME (coronal mass ejection) and SEP (solar energetic particle) release will be probable. The X5.4 flare this morning was accompanied by a full halo CME first appearing in the LASCO C2 field of view at 00:24 UT. View this powerful explosion below ------

The CME speed was around 2300 km/s. The arrival of the corresponding CME will hit Earth tomorrow, most probably in the evening. At least a strong (K = 7) geomagnetic storm will be possible. The flux of charged particles continue to increase, with the proton flux at energies above 100 MeV crossing the SEP event threshold (10 pfu) around 10 UT today.
The proton flux will most likely remain elevated at least until the arrival of the CME-driven shock tomorrow evening and possibly after that. SOHO/CELIAS and ACE confirm the detection of the interplanetary shock wave that arrived at 03:35 UT today. This shock wave was most probably associated with the halo CME erupted on March 4.
The plasma measurements by ACE are now corrupted by the on-going major charged particle event. The Earth is currently inside the post-shock solar wind flow with moderate speed (around 420 km/s) and elevated (around 15 nT) interplanetary magnetic field (IMF) magnitude. The north-south IMF component Bz is currently fluctuating near zero, but had extended intervals of negative values in the recent hours.
