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 presence of Solar Energetic Particles (SEPs) poses a serious health risk to humans in space, can result in increased radiation doses for high-latitude aircraft flights and constitutes a serious hazard for the micro-electronics and other hardware elements of satellites, aircraft and launchers. These groups of end users need reliable forecasts of possible enhancements in the radiation flux level, days beforehand, in order to plan flights, operations and EVAs (extra-vehicular activities). Enhancements of SEP fluxes result from explosive phenomena in …
For decades, high-energy aspects of the Sun have been studied using indirect imaging and spectroscopy in hard X-rays (HXR) by the pioneering RHESSI spacecraft. However, advanced understanding of small-scale energy releases and particle acceleration in the outermost layer of the Sun require better sensitivity and dynamic range, which can be achieved by using direct focusing X-ray optics. Almost six years ago, in 2012, the Focusing Optics X-ray Solar Imager (FOXSI) rocket experiment first imaged the Sun in hard X-rays (4 …
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 …
Happy holidays from the EGU office! This month we are happy to announce a new addition to the EGU awards and medals portfolio. The Katia and Maurice Krafft Award honours researchers who have shown exceptional efforts in geoscience communication and outreach. Submissions for this and other EGU 2020 awards and medals will be accepted from January until 15 June 2019.
This month we also announced that EGU is contributing EUR 132,000 to help fund over 20 training schools and conferences in 2019, including two Galileo Conferences. We have also launched a call for proposals for EGU members interested in organising Galileo Conferences from March 2020 to February 2021. Apply by 28 February 2019 to receive up to EUR 8000 in financial support, as well as significant organisational support, from the EGU.
Follow the links below for more news, including several updates and information regarding the EGU General Assembly. Remember, the deadline for abstracts is 10 January 13:00 CET. Before then, consider renewing your EGU membership to be part of the largest European geosciences union. EGU members are eligible to submit an abstract to the General Assembly and enjoy substantially reduced meeting registration rates, among other benefits.
