A major solar flare reaching X2.3 peaked at 21:54 UTC on Tuesday, October 29, 2013. This event originated from AR 1875 located on the west limb. A Type IV Radio Emission, indicating a strong coronal mass ejection, was associated with the event but since the region is no longer facing Earth it will be heading mostly away.
SUMMARY: X-ray Event exceeded X1
Begin Time: 2013 Oct 29 2142 UTC
Maximum Time: 2013 Oct 29 2154 UTC
End Time: 2013 Oct 29 2201 UTC
X-ray Class: X2.3
NOAA Scale: R3 – Strong
Potential Impacts: Area of impact consists of large portions of the sunlit side of Earth, strongest at the sub-solar point.
Radio – Wide area blackout of HF (high frequency) radio communication for about an hour.
ALERT: Type IV Radio Emission
Begin Time: 2013 Oct 29 2158 UTC
Description: Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections and solar radiation storms.
There are currently 9 numbered sunspot regions on the Earth side of the Sun. Beta-Gamma-Delta AR 1882 is approaching the center of the disk.
1873 – Alpha
1875 – Beta-Gamma-Delta
1877 – Beta-Gamma
1879 – Beta
1881 – Beta
1882 – Beta-Gamma-Delta
1883 – Beta
1884 – Beta-Gamma-Delta
1885 – Alpha
NOAA SWPC forecasters estimate 60% for M-class, and 25% chance for X-class solar flare in next 2 days
