Krzysztof Barczyński:   "Monitoring Solar Activity and Space Weather -databases and tools"


Abstract:

The outer layer of the Sun, known as the solar atmosphere, is a highly dynamic environment. Solar flares massive releases of electromagnetic energy and coronal mass ejections (CMEs) plasma eruptions from the solar atmosphere are two processes that have the most significant impact on the space environment between the Sun and Earth, and even beyond, throughout the solar system. The condition of this environment is what we define as space weather.

The aim of my presentation is to provide an overview of the space based instruments, tools, and databases used by the solar physics and space weather communities to monitor solar activity and space weather. We will focus on imaging data from the Solar Dynamics Observatory (SDO), as well as imaging and coronagraph data from Solar Orbiter and the Solar and Heliospheric Observatory (SOHO). Additionally, we will discuss flare catalogues (such as those based on GOES), and full disk EUV irradiance measurements from the PROBA-2 satellite. We will also introduce open-source tools such as JHelioviewer to provide an easy overview of the solar physics data. The obtained information is useful for identifying solar events that can impact on Earth's atmosphere and then ELF propagation.
