HELIO CDAW-3
Science Goals

Overview

We plan to study a similar set of topics to those covered in CDAW-2 but perhaps exploring them in different ways.

There are quite a few new people attending this time and they will without doubt stress the system in different ways. There have been many changes to the system, with new features added and fixes to a number of problems that have been identified.

HELIO is intended to provide something that us useful for the user so it is important to understand what is being done correctly and in which areas we need to change or correct things.

Material related to the papers used in CDAW-2 can be found here. Note that, if possible, we would like to identify papers that support the general objectives shown below. Using different data with modified objectives will help us determine how users want to interact with the data and use the system.

Observing events from different vantage points

The idea here would be to use the HELIO catalogues and other services to look for common events and then go out and try to find suitable data. Examples of this type of study might include:
  • Matching CMEs/ICMEs observed remotely from near Earth to in-situ at STEREO, and visa-versa
  • Matching CMEs detected in-situ at Ulysses with remote observations from near Earth
  • Try to match SIRs detected near Earth to remote observations at STEREO, and visa-versa

  • Matching flares detected by Ulysses matched with observations from near Earth

Following propagating phenomena

  • Observe the effects of propagating phenomena at multiple point within the inner heliosphere &ndash for example CMEs and other disturbances observed at Earth and Mars, Mercury and Venus, the STEREO missions, Ulysses and elsewhere.
  • Looking at effects observed further out in the Solar System.
  • Looking for the origins back on the Sun of effects observed at the Earth and other planets.
Sort of propagation tool is required to give the timing of when phenomena should be observed at different locations. We now how such tools within HELIO and need to determine if they provide what is needed.
