Which resulted in a Type 2 radio emission warning:
ALERT: Type II Radio Emission
Begin Time: 2012 Apr 24 0748 UTC
Estimated Velocity: 1029 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.
According to NOAA @ 22:00 on 4/23:
IA. Analysis of Solar Active Regions and Activity from 22/2100Z
to 23/2100Z: Solar activity has been at low levels for the past 24
hours. There are currently 8 active regions on the disk, with 5
regions having sunspots. The spotted regions on the disk all
remained rather quiet and stable throughout the period. However,
around plage Region 1461 (N10W19), two C-class events were observed
today
with associated Earth directed CMEs.
