Low solar activity, coronal hole stream incoming

Solar activity remains low with only C-class solar flares being reported. Sunspot region 2230 that we wrote about on Tuesday did not develop further and now has a fairly simple Beta-Gamma magnetic layout. We expect flaring activity at the C-level with only a very slight chance for an isolated M-class event as none of the sunspot regions currently on the earth-facing solar disk are very impressive. We keep our attention on the Sun as we can also see that a coronal hole has passed the central meridian and is expected to cause the arrival of a high speed solar wind stream in about two days from now with likely another round of enhanced auroral conditions on high latitudes in the week ahead.
