CME backwards propagation (1)

• Download

Workflow propagates an CME event from its observing point (planet/spacecraft) back to the sun. The propagation also provides the timing of this event at other points in space (planet/spacecraft)

Propagation of CME from the Sun (1)

• Download

Uses the processing service to calculate the objects (planets and observatories) which a CME might hit. Required longitude input is the longitude of the associated flare event.

• Download

This workflow uses the initial time period to search for time periods where Earth and Mars are not further appart than 80 degrees. These time periods are used to find Halo CME events. The CME events are forward propagated to Earth and Sun. Only events were the propagation model predicts that both planets are on the propagation path will be included in the final VOTable

Associate SEP events at Earth with flare, ... (1)

• Download

This is the implementation of a use case worked on during CDAW3 of the HELIO project. SEP events propagated backward from Earth to the Sun. We allow for +- 30 min around the predicted time to search for flare events. The timing of the flare event informs the search time for Type III radio event (time_start to time_peak) and for the CME event (time_start to time_start+1h). Results are presented in a mulitlayered VOTable.

Associate a Shock at Earth with Flare and ... (2)

• Download

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.

• Download

This workflow is querying the HEC for the fastest 100 CME of a given list (input parameter); it calculates the latitude from the postion angle; last step is to query the HFC for Active Regions and Filaments for the given time where the bounding box of the feature contains the longitude (feature must be on the correct side of the Sun.) Inputs: HEC list name (must contain fields: v, time_start, pa_width, pa) Outputs: v, time_start, pa_width, pa of the 100 fastest CME, VOTables for associated A...

• Download

The fastest CME is found from an interval of time, and propagated to Earth, in two steps, first to obtain the Solar wind speed at Earth and then propagated again with a more reasonable CME speed. The output produces Min-Max ETAs for each object in the heliosphere and the plots of the final propagation model. This Workflow was produced as one of the challenges in the HELIO CDAW-IV hosted at TCD

The workflow concept is below. Current workflow is proof of concept and works for default event.1. The initial query is to the stereo_hi_sw_transient list in a particular time range. From this catalogue we extract the longitude of the source of the transient, the longitude error, the start time (launch time of the transient) and the estimated time of arrival. The time of the event is then passed to the HELIO Instrument Location Service (ILS) to extract the Heliocentric Earth Equatorial longit...
