Sunspot region 2192 did it again! Less than 24 hours after the major X3.19 solar flare from yesterday, it now produced a major X1.04 (R3-strong radio blackout) solar flare at 17:08 UTC. This was already it's fourth X-class solar flare but again it looks like it did not launch a coronal mass ejection.
This solar flare looks very similar to the previous X-class solar flares. While coronagraph imagery is not yet available to confirm the launch of a coronal mass ejection, we can again conclude that due to the lack of any significant coronal dimming (traces in the solar corona of ejected material) there might not be a major coronal mass ejection associated with this event despite the long duration of the solar flare.
This post will be updated as soon as more information becomes available so keep checking back.

ALERT: X-Ray Flux exceeded M5 Threshold Reached: 2014 Oct 25 1659 UTC NOAA Scale: R2 - Moderate
SUMMARY: X-ray Event exceeded X1 Begin Time: 2014 Oct 25 1655 UTC Maximum Time: 2014 Oct 25 1708 UTC End Time: 2014 Oct 25 1811 UTC X-ray Class: X1.0 Optical Class: 3b Location: S12W30 NOAA Scale: R3 - Strong
Today's X1 solar flare was similar to yesterday's X3 solar flare. Again no coronal mass ejection as seen on this image from SOHO/LASCO.
