STRONG GEOMAGNETIC STORM POSSIBLE SUNDAY:
NASA Moon to Mars' modeling of today's Earth-directed solar storm indicate likely effects at Earth starting late on April 23.
A moderate (Kp=6), strong (Kp=7), or severe (Kp=8) geomagnetic storm is possible. pic.twitter.com/sPGZ1rmsaF— Space Weather Watch (@spacewxwatch) April 21, 2023
Halo CME: The clear outline of a halo coronal mass ejection (CME) is now visible following a filament eruption beginning at 17:25 UTC (Apr 21) in the vicinity of AR 3283. The X-Rays peaked at M1.7 and the event should be Earth directed with an impact to our geomagnetic field possible within 48-72 hours. Another update will be provided once a tracking model becomes available. Perhaps some good news for aurora sky watchers in the days ahead.
Texas may have higher than expected severe weather due to this event on Sunday.www.spc.noaa.gov/products/outlook/day1otlk.html
SUNDAY NIGHT NORTHERN LIGHTS FORECAST:
Aurora viewing will be possible in the United States on Sunday night into Monday morning before sunrise, provided that today's likely Earth-directed coronal mass ejection (CME) impacts Earth as forecast–more details below.
