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.
The 2018 Hannes Alfvén Medal is awarded to Eckart Marsch for fundamental contributions to our understanding of the kinetic processes and plasma turbulence in the heliosphere, as well as for work that helped HELIOS become a successful mission and initiated the Solar Orbiter.
The 2018 Julius Bartels Medal is awarded to Ilya G. Usoskin for his key contributions to long-term changes of cosmic rays and solar activity, qualifying him as a founder of the space climate discipline.
The 2018 Division Outstanding Early Career Scientists Award is awarded to Natasha L. S. Jeffrey for her outstanding achievements in improving the standard model of fast electrons produced in solar flares, thereby eliminating the long-standing low-energy cut-off uncertainty.
The 2018 Outstanding Student Poster and PICO (OSPP) Awards is awarded to Irina Zhelavskaya Systematic analysis of machine learning techniques for Kp prediction in the framework of the H2020 project ‘SWAMI’
The 2018 Outstanding Student Poster and PICO (OSPP) Awards is awarded to Pauli Väisänen Long-term evolution of the power-law spectrum of galactic cosmic rays in 1953-2016
The 2017 Hannes Alfvén Medal is awarded to Eric R. Priest for his fundamental contribution to the understanding of the mathematical complexity and physics of magnetic reconnection and the magnetic coupling of the convection zone with the solar atmosphere.
The 2017 Julius Bartels Medal is awarded to Tuija I. Pulkkinen for her key contributions in solar-terrestrial science, scientific management, academic leadership, and services to the space community.
The 2017 Outstanding Student Poster and PICO (OSPP) Awards is awarded to Emma Anderberg Reconstructing the 11-year solar cycle length from cosmogenic radionuclides for the last 600 years
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 …
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 …
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 …
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 …
This month, we have announced changes to the EGU General Assembly 2019 schedule, which aim to give more time for all presentation types. Check our news announcement for more information. If you’d like to apply for funding to attend the meeting next year, make sure to submit your conference abstract by 1 December! In other news, we have opened applications to the EGU General Assembly 2019 mentoring programme, and are advertising a job opportunity for geoscientists with science communication experience to work at the meeting.
Also this month, we opened the call for applications for EGU Public Engagement Grants, and have announced the creation of the EGU Working Group on Diversity and Equality. In addition, we opened the EGU Autumn 2018 Elections for the next EGU Treasurer: you have until 30 November to cast your vote. We’ll be announcing the results early next week.
