Bulletin

NOAA 2297 is a compact and magnetically complex region still close to the southeast limb. Over the last 24 hours, it has only produced C1 and C2 flares, but it retains its potential on a strong flare over the next few days. As this region rotates further onto the solar disk, any associated coronal mass ejection (CME) may gradually become more earth-directed. Two other sunspot groups are hardly visible and quiet. No earth-directed CMEs were observed. Proton flux was at nominal levels. There's a good chance on M-class flaring. Quiet to active geomagnetic conditions were observed. Solar wind speed has gradually been increasing, from about 460 km/s at the beginning of the period to its current 550 km/s. Bz oscillated between -9 and +9 nT. The interplanetary magnetic field was directed away from the Sun. A negative polarity equatorial coronal hole (CH) will reach the central meridian late on 09 March. Quiet to active geomagnetic conditions are expected, under the influence of the high speed stream from an extended coronal hole. There's a slight chance on a minor storm episode.
