CME Scoreboard: Prediction Detail

Prediction for CME (2017-09-06T12:24:00-CME-001)

CME Observed Time: 2017-09-06T12:24Z
iSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/13013/-1
CME Note: Associated with X9.3 flare from AR 12673.
CME Shock Arrival Time: 2017-09-07T22:30Z
Observed Geomagnetic Storm Parameters due to CME:
Max Kp: 8.0
Dst min. in nT: -142
Dst min. time: 2017-09-08T02:00Z

Predicted Arrival Time: 2017-09-08T06:00Z (-2.0h, +2.0h)
Prediction Method: Ooty IPS
Prediction Method Note:

Interplanetary scintillation (IPS) observations by Ooty
Radio Telescope (ORT) of a large number of radio sources allow 
to estimate scintillation index - so called g-value.  
The g-value represents the turbulence level of the solar-wind.
The presence of a transient (CME) and its associated disturbances can be identified by the enhanced
level of g-value. Everyday observations IPS observations allow to track a transient (CME) propagation in the heliosphere.

Our IPS observations show that the CME associated with the X9.3 flare
is propagating with a velocity of ~900 - 1000 km/s, at a distance of ~0.5 AU
at about 7 UT.

The CME is expected to reach the near-earth environment ~5 to 7 UT on
08 SEP 2017.

Lead Time: 6.00 hour(s)
Difference: -7.50 hour(s)

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.
