Bulletin

Over the past 24 hours there were several C-class flares and 4 M-class flares which were produced by NOAA AR (Active Region) 2297, which is currently located at S20, 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 M4.2 flare on 2015-Mar-12 peaking at 14:08UT, an M2.7 flare on 2015-Mar-12 peaking at 21:51UT, an M1.2 flare on 2015-Mar-13 peaking at 04:01UT and an M1.8 flare on 2015-Mar-13 peaking at 06:07UT. AR 2297 has shown little magnetic evolution with a small amount of flux emergence, which may lead to future eruptions. AR 2299 rotated into view and exhibits a small amount of activity. AR 2298 has shown little activity. There were no discernible Earth directed CMEs over the past 24 hours. There is a large filament located between S15W90 and S50E20, however this has remained, and appears, stable. The solar wind speed has remained roughly constant over the past 24 hours around 425 km/s. The total magnetic field has slightly increased from 5 nT to 7 nT, and the Bz component has remained mainly positive over the past 24 hours. The Bz has ranged between +6 and -9 nT. Geomagnetic conditions ranged between Kp index 0-3 (NOAA) and local K index 0-3 (Dourbes) over the past 24 hours. A transient coronal hole is currently located at S05W50, this may produce enhanced solar wind speeds. AR 2297 and AR 2299 produced several small CMEs over the past 24 hours.
