B. Proton Events
C. Geomagnetic Activity Summary
The geomagnetic field ranged from quiet to minor storm conditions. An interplanetary shock passed the ACE spacecraft around 19/1020 UTC. This activity is likely associated with the CME which occurred late on 15 March. A brief magnetopause crossing was observed on GOES-8 (W075) at 19/1807 UTC.
D. Stratwarm
Stratwarm alert exists stratwarm Monday. Slowly increasing temperatures over the polar region and weakening of the cyclonic circulation. End of this alert period.
