What is HELIOGate for ?
Study the interactions between the Sun and the other bodies of the Solar System.

HELIOGate
The HELIO Gate portal offers to the Heliophysics community an easy and intuitive way of performing repetitive and time-consuming actions.

Heliophysics
• In heliophysics, we are interested in how an event on or near the solar surface can propagate through the heliosphere and affect a planetary environment
• Searches should identify interesting time intervals based on a combination of event, features, etc. metadata
• There are concerns about the quality and integrity of the metadata and whether it is adequate to support the searches we would like to undertake

Propagation Model
• A propagation model is used to help determine which observations, where and when may be of interest in order to satisfy the user's search criteria.

Fastest CMEs Propagation
This workflow is used to investigate one of the most relevant events in HELIOphysics; Coronal Mass Ejections. The propagation of these events is studied throughout the Solar System by the means of the execution of the SHEBA propagation model on the HELIO Processing Service.
