CME Scoreboard

Go to CME Scoreboard Web App


The CME Scoreboard is part of the the CME Arrival Time and Impact Working Team in the Community-wide International Forum for Space Weather Modeling Capabilities Assessment.

The CME Scoreboard (developed at the Community Coordinated Modeling Center, CCMC) is a research-based forecasting methods validation activity which provides a central location for the community to:

  • submit their forecast in real-time
  • quickly view all forecasts at once in real-time
  • compare forecasting methods when the event has arrived

Using this system:

  • Anyone can view prediction tables
  • Registered users can enter in your CME shock arrival time forecast after logging in:
    • Registered Users: Begin by finding your CME under the "Active CMEs" section, then click "Add Prediction" and select your forecasting "Method Type" from the list.
    • Power Users: If you do not see your CME listed under the "Active CMEs" section, click "Add CME" to get started (Email M. Leila Mays to request power user privileges). To enter the actual CME shock arrival time, click "Edit CME" after you are done entering your prediction(s).
    • To register for an account, please email M. Leila Mays with your name, affiliation, and email address.
  • See "CME Propagation Models" below for a list of registered methods and how to add your model for this effort.
  • Click here for more detailed instructions [PDF].


  • To receive periodic announcements and/or automated email notifications when a new CME is added to the CME Scoreboard, please send an email to M. Leila Mays with your name and email.


CME Propagation Models

This is a subset of space weather forecasting CME propagation models (see below for references) that can be selected as the CME arrival time "Prediction Method" in the CME arrival time Scoreboard. If you would like to register your prediction method, please send an email to M. Leila Mays or Yihua Zheng with your model/technique details. All prediction methods are welcome and all are encouraged to participate in this research activity.
