NOAA region 12371 produced another long duration X-ray flare overnight.  This flare peaked at level R2 on the NOAA Space Weather Scales for X-ray events.  SWPC forecasters are currently analyzing all available data to determine if the Cornoal Mass Ejection (CME) from this X-ray event will impact the Earth.  Stay tuned!
