Over the past 24 hours there were several C-class flares and 3 M-class flares, which were produced by NOAA AR (Active Region) 2297, which is currently located at S15E25, and is classified as a Beta-Gamma-Delta region under the Mount Wilson magnetic classification system. The largest flares recorded over the past 24 hours, all produced by AR 2297, were an M2.9 flare on 2015-Mar-10 starting at 23:46UT, an M1.8 flare on 2015-Mar-11 peaking at 07:18UT and a M2.6 on 2015-Mar-11 peaking at 07:57UT. AR 2297 has shown some evolution with significant flux emergence, which may lead to future eruptions. There were no discernible Earth directed CMEs in the past 24 hours. AR 2297 produced continual out-flows throughout the past 24 hours and several small CMEs (Coronal Mass Ejection) directed to the Northeast. There is a large filament located between S05W90 and S40E50, however this has remained, and appears, stable. The solar wind speed has been slowly increasing over the past 24 hours from 350 km/s to 400 km/s. The total magnetic field has increased from around 6 nT to 8 nT, and the Bz component remained mainly positive. The Bz has ranged between +8 and -10 nT over the past 24 hours. Geomagnetic conditions ranged between Kp index 1-3 (NOAA) and local K index 0-3 (Dourbes) over the past 24 hours. A transient coronal hole is currently located at W20, this may produce enhanced solar wind speeds. AR 2297 produced several small CMEs and continual flows over the past 24 hours, as this region rotates towards disk center it may produce more geoeffective events.
