Division on Solar-Terrestrial Sciences

President: Margit Haberreiter (st@egu.eu)
Deputy President: Olga Malandraki (omaland@astro.noa.gr)

The ST Division considers all aspects of solar and heliospheric physics, specifically the solar-terrestrial connection. It covers the physical processes occurring on the Sun, in the solar wind, as well as in Earth's magnetosphere and ionosphere. Solar activity (e.g. coronal mass ejections, solar flares, solar energetic particle events) and the response of the near-Earth space environment to these solar phenomena are studied on a wide-range of temporal and spatial scales. Data analysis and interpretation of space-borne and ground-based data, as well as theoretical studies and different modeling techniques are used to better our understanding of how our local star defines the neighborhood that we live in.

EGU for Early Career Scientists

This months post is written by the ST Divisions Early Career Scientist representative, Theresa Rexer. Are you ready for the EGU general assembly 2019? Got your abstract ready and submitted? No, what? Too early you say? No funds? As your Early Career Scientist Representative, let me tell you why now is the perfect time to start planning your trip to Vienna in April next year. Especially if you are an Early Career Scientist! EGU2019 aka the best meeting for Early …


A close-up journey to the Sun: The Parker Solar Probe Mission

A close-up journey to the Sun: The Parker Solar Probe Mission

Almost two months ago, in August 12, 2018 Parker Solar Probe (PSP) launched by NASA on a Delta IV Heavy rocket from Cape Canaveral, Florida. This is a long-awaited mission from the Heliospheric community. The first to explore the Sun within distances of ~0.167 AU (or 25 million kilometers) at its perihelia. Its ancestors were the successful Helios -A and -B spacecraft, a pair of probes launched into heliocentric orbit for the purpose of studying solar processes, that orbited our …


Cosmogenic Radionuclides - The quest of studying the solar activity of thousands of years

Cosmogenic Radionuclides - The quest of studying the solar activity of thousands of years

Thanks to the invention of the Neutron Monitor in 1948 and multiple spacecraft which monitor the cosmic ray environment since 1970’s we now have a constant record of the solar activity over almost 70 years. Information prior to this space era, however, are rare and take us back in time only to the late 1930s, when ionization chambers have been introduced. This of course allows us only a narrow view on the solar behaviour compared to the age of the …


SunPy: a Python solar data analysis environment

SunPy: a Python solar data analysis environment

Introduction For many years now we know that our star the Sun influences the Earth in many different ways, via the total solar irradiance, solar energetic particles and coronal mass ejections. Understanding the influence of the Sun on the Earth requires many different types of measurements. For example, NASA’s Solar Dynamics Observatory (SDO) spacecraft, produces over 1 terabyte of data per day (Pesnell et al., 2012), the bulk of it in the form of 4096 by 4096 pixel images in …

Current issue of the EGU newsletter

Earlier in October, we announced the winners of the 2019 EGU awards and medals: 45 individuals who have made significant contributions to the Earth, planetary and space sciences and who will be honoured at the 2019 EGU General Assembly next April. We have also announced the winners of the Outstanding Student Poster and PICO (OSPP) Awards corresponding to the 2018 General Assembly, which you can find on our website. Congratulations to all!

This month, we also opened the call for abstracts for the EGU 2019 General Assembly. If you are interested in presenting your work in Vienna in April, make sure you submit your abstract by 10 January 2019, 13:00 CET. If you would like to apply for a Roland Schlich travel grant to attend the meeting, please submit your abstract no later than 1 December 2018. All 2019 EGU members will be able to submit abstracts to the 2019 meeting. With a few exceptions, only one abstract as a first author will be permitted. Please find more information on the EGU website.

In November, EGU 2018 members will have the opportunity to vote for the next EGU treasurer in the EGU Autumn elections. Check the elections page on our website for more information.
