Associate a Shock at Earth with Flare and CME event on Sun

Download Workflow

Using start date and end date all shock events at Earth are backpropagated to the Sun. Arround the time all flares (above certain levels) and cmes are assoicated. The possition of the flare and speed of the CME are used to forward propagate the event to Mars.

Connect flare events with proton events on... (4)

Download

This workflow uses flares listed in the goes_sxf_flare list, checks wether this flare is connected to Earth via the Parker spiral, and looks for proton events at earth listed in the goes_proton_event list. The flare listing and the proton listing is combinded into a VOTable output.
