Coronal Hole to Face Earth
October 16, 2021 @ 00:45 UTC
Good evening. Solar activity was at very low levels during the past 24 hours with only a single B9.7 flare observed towards the west limb in the vicinity of departing AR 2882 and 2885. Unless another active region forms, the visible disk will be at risk of going spotless for the first time since September 17th.

A couple of coronal holes, most notably large CH #13, will be turning into an Earth facing position over the next several days. A coronal hole stream is predicted to reach Earth beginning Monday, October 18th and lead to a geomagnetic enhancement at higher latitudes. Depending on if the coronal hole maintains its size over the next week, the solar wind influence could be productive enough to lead to a geomagnetic storm. More updates later this weekend.
