NOAA AR 1748 rotated into view, it is still not possible to infer its magnetic configuration but it is a big region with mixed magnetic polarities. It produced two X-class flares in past 24h and can produce more. The first one was an X2.8 with peak at 16:05 UT on May 13, the second one an X3.2 at 01:11 UT today. Both were related to radio bursts and fast limb CMEs. The first CME has a speed of 1500 km/s in the LASCO C3 field of view (decelerated with respect to the 1800 km/s seen in C2), while the second one was travelling at 1900 km/s in LASCO C3 (accelerated from the 1600 km/s measured in C2). Due to the source region location right at the limb, we expect at most a shock arriving to the Earth early on May 15 (09:00 UT for the first one and 13:00 UT for the second one). There is also a CME from May 12 expected to arrive around the same time as the first CME from yesterday. The second X flare and corresponding CME produced also a rise on the proton flux, which is still below the threshold and seems stable for the moment. NOAA AR 1745 has also potential for M flares. High solar activity is expected for the next 48h. Geomagnetic conditions are currently quiet. The possible arrival of a shock from the two halo CMEs and a mild fast speed stream from a coronal hole may increase conditions to active and possible minor storm levels in the next 48h.
