Summary

The primary motivation of this workshop is the availability of a wealth of coronagraph data from space missions that can be effectively combined with ground based observations in developing countries to make significant progress in some key issues in space science. Understanding the behavior and evolution of shocks near the Sun is very important in understanding the particle acceleration process and their space weather consequences. Type II bursts from ground based instruments such as CALLISTO provide information on the shock nearest to the Sun, while the space based radio instruments provide information on shocks at a couple of solar radii from the Sun and beyond. Thus there is a great benefit in combining space and ground based data for a better understanding of these solar shocks. After the workshop, the participants will be able to perform correlative data analysis on coronal mass ejections and shocks, thus contributing to the progress of this important field in Sun-Earth connection.

Workshop details

Shock waves represent a universal process from the solar corona to the heliospheric termination shock and supernova shocks to shocks in the intergalactic medium. Spacecraft such as the Solar Heliospheric Observatory (SOHO), the Solar Terrestrial Relations Observatory (STEREO), Wind, and the Advanced Composition Explorer (ACE) missions routinely pass through shocks driven by coronal mass ejections (CMEs) in the interplanetary medium and thus provide excellent details on the shock properties and the energetic particles contained in them. While these in situ measurements are extremely valuable, more important is the origin of these shocks very close to the Sun – typically only about 350,000 km above the solar surface. Such shocks have to be observed remotely using ground based radio telescopes in the form of type II radio bursts. Early detection of these shocks is also important because they cause particle increase at Earth during their Earth arrival and sudden commencement of geomagnetic storms. One of the simple radio instruments capable of observing solar radio bursts is the Compound Astronomical Low-cost Low-frequency Instrument for Spectroscopy and Transportable Observatory (CALLISTO) deployed worldwide by ETH Zurich. There is a concentration of these instruments in East Africa – South Asia region that acquire valuable data on solar radio bursts. Thus a workshop to combine the radio and coronagraph data to study solar eruptions is highly valuable in getting a large number of young people trained in this field so they can make important contributions to the study of Sun-Earth connection.

The space data to be utilized in the workshop are readily available online at the CDAW Data Center, NASA Goddard Space Flight Center (http://cdaw.gsfc.nasa.gov). Ground based radio data are also currently made available in the web site http://www.e-callisto.org/. The Wind and STEREO radio data are also available in several formats that can be readily downloaded for further analysis. We propose to introduce data analysis tools such as python that can handle the png and fits files. Well before the workshops, we shall make sure that the participants have a software that can handle the data (IDL, Python, or MATLAB).

Participants: (Application is closed now)

The target participants are Masters and PhD students, young postdocs and staff involved in hosting e-CALLISTO network. About 30 participants are expected from countries such as Algeria, Egypt, Ethiopia, India, Indonesia, Kenya, Malaysia, Mauritius, Pakistan, South Africa, and Sri Lanka. All these countries currently host one or even more CALLISTO radio instruments. 

Interested people shall send the following document as soon as possible to Gebregiorgis Abraha ggabraha(at)yahoo.com.hk with copies to: Nat Gopalswamy nat.gopalswamy(at)nasa.gov and  C. Monstein monstein(at)astro.phys.ethz.ch
- A short CV
- An actual photo
- A recommendation letter

There will be two levels of support: 
(1) Financial support will be provided only to those coming from African countries.- For others, they should come on their own funding. 
(2) People from developing countries will be provided with lodging and meals.
