UVCS WG ON
Empirical Models of CME's, transients, active regions, flares, quiet corona

Chairperson:

Ester Antonucci

Group Coordinator:

Daniele Spadaro

Main scientific purposes:

  1. characterize coronal phenomena such as coronal mass ejections and transients by determining the dynamics of the plasma in terms of outflow velocity, l.o.s. velocity, rms value of the velocity distribution, the geometry as derived with the different line emissions, possibly the plasma temperature, ionization conditions and element abundance;
  2. characterize in the same manner the mid-latitude coronal regions outside streamers;
  3. investigate the effects on the extended corona of solar activity, namely of active regions and flares.

The first goal of the working group will be to discuss how to optimize the observations to get a homogeneous and as complete as possible set of data in order to achieve the best empirical definition of phenomena and regions under investigation. We presume that the observational approach of the working group and the emphasis on the different topics of interest will change progressively through the solar cycle (long life to UVCS!).
