Over the past 24 hours solar activity has been low. No significant flares have been recorded. Active Region (AR) 2699 (Mcintosh class:Dai; Mag. type:Beta) has been most active, showing considerable flux emergence and cancellation. The greater than 10MeV proton flux remained at background levels over the past 24 hours. A halo CME was observed in the SOHO/LASCO C2 field of view at 01:25 UT yesterday (2018-Feb-12). The CME has a projected speed of approximately 509 km/s and is anticipated to reach the Earth on 15-Feb-2018 at approximately 12:00 UT. Over the next 24 hours flaring activity is expected to be at the C-class level with a medium probability of M-class flares. The solar wind speed has decreased from around 325 to 300 km/s over the past 24 hours. The total magnetic field strength has remained around 5 nT. The Bz component was largely positive, fluctuating between -5 and +5 nT. Geomagnetic conditions ranged between Kp index 0-2 (NOAA) and local K index 0-2 (Dourbes) over the past 24 hours. A large positive polarity coronal hole just passed the central meridian and may enhance solar wind speeds at Earth in a couple of days. The above mentioned halo CME should reach the Earth around 15-Feb-2018 at approximately 12:00 UT and may also enhance solar wind conditions. Geomagnetic conditions are expected to be quiet to unsettled.
