Proton Events: None C. Geomagnetic Activity Summary: Solar activity is expected to be moderate. Region 9893/9901 complex has been active and has two delta configurations. The potential for M-class events is good. Region 9906 and 9907 are developing and have a slight chance of M-class events. D. Stratwarm: None E.
