However, we do not expect any of them to affect the Earth. With just one active region on the solar disk, the solar activity otherwise remains quiet. We expect quiet geomagnetic conditions with a possible disturbance on Nov 27th due to a fast solar wind stream originating from a coronal hole. For now, the all quiet alert remains valid.
