Prediction for CME (2021-07-24T00:36:00-CME-001)

CME Observed Time: 2021-07-24T00:36Z
iSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/17370/-1
CME Note: Visible to the east in SOHO LASCO/C2 and C3; halo in STEREO A COR2. Associated with eruption from AR 12849 (S18E47), visible in SDO AIA 171/193/304 beginning 2021-07-23T23:42Z, and associated with C4.3 flare beginning 2021-07-23T23:54Z. From Lan Jian: no clear features of iCME arrival found on 07-26 to 07-28 (stream interface seen at ~2021-07-28T04:50Z).
CME was not detected at Earth.

# Forecast_summary_metadata:
#   AlertIssued is the alert issue time
#   PredictStart is the event predicted start time
#   PredictPeak is the event predicted peak time
#   EL is the wait time in minutes before issuing another alert
#   GX is the alert level on NOAA G scale ranging from G0 to G5
#    G4, G5: WARNING: is issued when a hazardous event is occurring, 
#        is imminent, or has a very high probability of occurring. 
#        A warning is used for very active conditions posing a threat 
#        to life or property.
#    G3: ADVISORY: is issued in active to very active conditions 
#        that may cause significant inconvenience, and if caution 
#        is not exercised, it could lead to situations that may threaten 
#        life and/or property.
#    G2: WATCH: is issued when the risk of a hazardous event has increased 
#        significantly, but its occurrence, location, and/or timing is 
#        still uncertain. It is intended to provide enough lead-time in 
#        active conditions so that those who need to set their plans in 
#        motion can do so.
#    G1: ALERT: is issued when an event threshold is crossed. It contains 
#        information that is available at the time of issue.
#    G0: MONITORING: is issued when the geomagnetic conditions are being 
#        actively monitored with information that is available at the 
#        time of issue.
#   DST is the predicted peak (deepest perturbation) of event in nT
#   Pr is the % probability of occurrence of event at epoch
#   Sr is the source of forecast (daily Probability (GP or SP), Solar Event (SO), or None (NN))
#   Vel is the velocity of the ejecta leaving the solar surface in km/sec
#   Status of the combined predicted Dst events relative to NOAA G-scale
#      AC = all clear (>-10 nT) (G0 monitoring)
#      UN = unsettled (-33 to -10 nT) (G1 alert)
#      SE = small event predicted (-33 to -48 nT) (G2 watch)
#      ME = medium event predicted (-48 to -198 nT) (G3 advisory)
#      LE = large event predicted (-198 to -350 nT) (G4 warning)
#      LX = very large event predicted (-350 to -400 nT) (G5 warning)
#   CID is the Class ID for the event composed of a letter flare class and Xhf magnitude
#      C = small flare class
#      M = medium flare class
#      X = large flare class
#      0-300 = Xhf magnitude of event
#   Bz is the estimated dominant Bz direction at Earth (N = northward, S = southward)

CCMC Rules of the Road: CCMC requests that users notify the CCMC, CME model/technique developers and submitting forecasters/researchers before performing event and validation studies with data from the CME Arrival Time Scoreboard. It is recommended that such studies be performed with the knowledge and collaboration of developers and submitting forecasters/researchers.

If you are looking for the official U.S. Government forecast for space weather, please go to NOAA's Space Weather Prediction Center (https://swpc.noaa.gov). This "Experimental Research Information" consists of preliminary NASA research products and should be interpreted and used accordingly.
