G1-Minor Geomagnetic Storms Observed
An interplanetary shock was observed at the ACE spacecraft at approximately 19/2310 UTC (07:10 PM Eastern). A geomagnetic sudden impulse was subsequently recorded at magnetometer sites around the globe at 19/2355 UTC (07:55 PM Eastern). G1-Minor geomagnetic storm conditions have been observed and G2-Moderate conditions are expected as a result of this CME arrival.
