There is an unnumbered active region to the northwest of AR 2735 that developed quickly in the last hours. It produced a C4.8 flare peaking at 11:18 UT and several B-class flares. A small dimming was also visible in relation to these flares, there are no coronagraph data yet to search for an associated CME. This will be confirmed later as the data become available. There is one numbered active region visible on the solar disk (NOAA AR 2735 with beta magnetic field configuration). This region has grown in size and number of sunspots. A small dimming was seen from this AR on 18 March at 14:27 UT, for which no obvious CME could be found in the data. More C-class flares can be expected, M-class flares are possible.

Solar protons have remained at background levels over the past 24 hours.

The solar wind speed did not reach high values (lower than 420 km/s) in the high speed stream that was expected for yesterday, the interplanetary magnetic field remained below 8 nT. Therefore, geomagnetic conditions reached only unsettled levels (K = 3). At present, the solar wind speed is at 400 km/s with interplanetary magnetic fields of 4 nT. Quiet to unsettled conditions can be expected in the coming hours.
