From the current sideways perspective, the corresponding sunspot region cannot not be well imaged yet and therefore the flaring forecast is uncertain. C-class flares are surely possible with a decreasing chance for an isolated M-flare. Geomagnetic conditions are expected to remain quiet until a coronal hole has crossed the solar central meridian towards the end of this week. Meanwhile ... a happy 2008!
