- Purpose:
-
Charged particles are constantly streaming outward from the Sun. When events such as Coronal Mass Ejections (CMEs) occur on the Sun, an Interplanetary (IP) shock may be generated, causing the incoming particle flux observed at or near Earth to increase by orders of magnitude. Sharp increases in particle intensity are referred to as Energetic Storm Particle (ESP) events, and they are important because they present a radiation hazard for electronics and humans in Earth orbit. The purpose of this project, a continuation of the Real-time Interplanetary Shock Prediction (RISP) project, is to detect and predict the arrival of IP shocks using real-time data from NASA's Advanced Composition Explorer (ACE) spacecraft.
- Input:
-
Observations from two ACE instruments:
- Output:
-
Real-time alerts, predictions and display at five-minute intervals. If the onset of an event has been detected and validated, an operational display is shown indicating the estimated time until arrival (at the location of ACE, which is the first Lagrange). We also show graphs of predictions over the past two hours and the past three days. Finally, we include plots of the input data and output predictions for each event detected in the past.
