Geomagnetic Activity Summary: The geomagnetic field was mostly unsettled to active with isolated minor storm periods during local nighttime hours. Solar wind speed began a gradual rise from near 500 km/s midway through the period to approximately 650 km/s by the end of the period. D. Stratwarm: None E.
