Solar activity was at very low levels. The visible solar disk was spotless.

Solar activity is expected to continue at very low levels.

The geomagnetic field was at quiet levels. A co-rotating interaction region was seen at the ACE spacecraft at 19/1715Z elevating solar wind speeds to approximately 420 km/s. A sudden impulse (11nT) was detected at the Boulder magnetometer at 19/1811Z. At the end of the forecast period wind speed was approximately 440 km/s.

The geomagnetic field is expected to range from quiet to active levels. On day one (20 November), expect mostly quiet to unsettled levels. On days two and three (21 to 22 November), conditions are expected to increase to unsettled to active levels, due to a coronal hole high speed stream moving into a geoeffective position. Isolated minor storm levels at middle latitudes, and major storm periods at high latitudes are also possible on 21 and 22 November.
