Additional Comments

Mild disturbances in the solar wind led to some ACTIVE periods during the last 24 hours. There remains a slight chance for brief isolated ACTIVE periods, but geomagnetic conditions are expected to remain largely QUIET throughout the forecast intervals.
A filament eruption occurred yesterday off the southwest disc. Coronagraph imagery during this time is limited, but it is likely that any CME related to this event is directed south and west of the Earth, so we are not anticipating any impact.
There appears to have been another filament eruption this morning nearer the centre disc. Further analysis is required but if there is an associated CME is could become geoeffective late in the third forecast interval.
