Coronal hole stream, sunspot region 2434
Tuesday, 13 October 2015 22:59 UTC
Our planet is currently inside a weak to moderately strong coronal hole solar wind stream. The direction of the IMF (Bz) is mostly southward and a Kp-value of 4 which stands for active geomagnetic conditions is currently being observed.
A more trans equatorial portion of the earth-facing coronal hole has now rotated past the central meridian so more fast solar wind will be on it's way. We will likely continue to see enhanced geomagnetic conditions for at least the next 3 days and it is very much possible that we will see minor G1 geomagnetic storming conditions in the coming days.
Sunspot region 2434
Old sunpot region 2428 (now it has number 2434) has rotated back onto the earth-facing disk and produced a couple of C-class solar flares today, including a C9 event at 14:11 UTC. This sunspot region is surrounded by faculae and this suggests it is in a state of decay. We can not yet analyse it's magnetic layout but it should be monitered based on the solar flares it produced today.
