Geospace Discussion (SWPC) .24 hr Summary... The geomagnetic field was mostly quiet to unsettled, with an isolated period of G1 (Minor) geomagnetic storming, due to waning CH HSS influence. .Forecast... The geomagnetic field is expected to be at quiet to unsettled levels, with a chance for isolated active periods on 19 Jan as elevated wind speeds from the recent CH HSS persist. The nearby passage of the 16 Jan CME could cause occasional periods of unsettled conditions later on 20 Jan and into 21 Jan.
