At 07:51 UTC, November 16, 2012 a C1.4 solar flare peaked from Active Region 1613. About the same time, a large solar prominence was observed off the Sun’s eastern limb. Prominence produced Coronal Mass Ejection (CME), however it does not appear to be Earth directed. Both events can be seen in SDO movie attached below.

 

prominence is a large, bright feature extending outward from the Sun’s surface, often in a loop shape. Movie credit: NASA/SDO and the AIA, EVE, and HMI science teams.

At 15:39 UTC (November 16, 2012) another C-class event was recorded. This time a C8.4 with Type II Radiation associated, indicating that Coronal Mass Ejection (CME) was probably present:

Space Weather Message Code: ALTTP2
Serial Number: 829
Issue Time: 2012 Nov 16 1605 UTC

ALERT: Type II Radio Emission
Begin Time: 2012 Nov 16 1540 UTC
Estimated Velocity: 511 km/s
Description: Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event.
