Waiting for the next stream, Quiet Sun

Geomagnetic conditions are quiet right now but we did had one period where we reached the G1 minor geomagnetic storming threshold yesterday due to what was likely a minor coronal hole solar wind stream that carried a mostly southward Bz component of the IMF. Aurorae were seen from multiple high latitude and even upper middle latitude locations like:

What likely are the remains of sunspot region 2422 has rotated into view and it is now known as sunspot region 2437. While there were two M-class solar flares from this area on 17 October, we have to conclude that the spots which are visible right now pose no threat for further M-class activity.

All the other sunspot regions on the disk are also not complex enough for M-class activity. Beta-Gamma sunspot region 2436 and sunspot region 2434 are however likely candidates for C-class activity.
