## Summary:

C-type CME detected by STEREO A / SOHO. 

Start time of the event: 2021-07-26T16:48Z.

Estimated speed: ~610 km/s.

Estimated opening half-angle: 35 deg.

Direction (lon./lat.): -8/-3 in Heliocentric Earth Equatorial coordinates.

Activity ID: 2021-07-26T16:48:00-CME-001

Based on preliminary analysis by the Moon to Mars Space Weather Office and heliospheric modeling carried out at NASA Community Coordinated Modeling Center, it is estimated that this CME may affect STEREO A (glancing blow).  The leading edge or flank of the CME will reach STEREO A at 2021-07-30T01:30Z (plus minus 7 hours). 

The simulation also indicates that the CME may impact NASA missions near Earth. Simulations indicate that the leading edge of the CME will reach NASA missions near Earth at about 2021-07-29T15:17Z (plus minus 7 hours). The roughly estimated expected range of the maximum Kp index is 3-4 (below minor).
