## Summary:

C-type CME detected by STEREO A / SOHO. 

Start time of the event: 2020-12-01T07:12Z.

Estimated speed: ~774 km/s.

Estimated opening half-angle: 35 deg.

Direction (lon./lat.): -45/8.3 in Heliocentric Earth Equatorial coordinates.

Activity ID: 2020-12-01T07:12:00-CME-001

Based on preliminary heliospheric modeling carried out at NASA Community Coordinated Modeling Center/Space Weather Research Center, it is estimated that this CME may affect Mars and STEREO A.  The leading edge of the CME will reach Mars at 2020-12-06T07:51Z and STEREO A at 2020-12-03T12:35Z (plus minus 7 hours). 

The simulation also indicates that the CME may have a glancing blow at NASA missions near Earth. Simulations indicate that the flank of the CME will reach NASA missions near Earth at about 2020-12-04T21:28Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 2-3 (below minor).
