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.

Events organised by the ST Early-Career Scientist (ECS) Team during EGU22: We would like your feedback!
Now that EGU22 is over, it is time to gather some feedback! While you can provide your comments and suggestions on the General Assembly as a whole via the dedicated form available through the EGU22 website (see “Feedback” tab in https://www.egu22.eu/), the ST Division’s Early-Career Scientist (ECS) Team would very much appreciate getting feedback on the various events they have organised during this first-ever fully hybrid EGU General Assembly. It is very important for us to know what worked and …

Resolving the very fine details of the Sun in low frequency radio
The Sun is an active radio emitter, it produces radio emissions in a wide frequency range from kHz to THz. The solar atmosphere has a complex distribution of magnetic field, plasma density, and temperature. These different properties of the solar atmosphere will result in different radio emission features at different frequencies. In principle, the plasma density decreases with the heliocentric distance, and higher density plasma tends to generate higher frequency radio emissions, thus the features in lower frequency correspond to …

Initiation and Heliospheric Evolution of a stealthy solar eruption
In the early 1970s, when Coronal mass ejections (CMEs), massive eruptions of magnetized solar plasma into interplanetary space, were first discovered, they were assumed to be always associated with the energetic solar phenomenon like solar flares, prominences, etc. With improved coronagraphic and multi-wavelength observational instruments, a class of CMEs emerging from the streamers was found and named Streamer-blowout CMEs (SBO-CMEs; Vourlidas et al. 2018). These CMEs have signatures of flux ropes but have no direct association with solar active regions, …

Current issue of the EGU newsletter
In the May issue of The Loupe, we read of new ways to make science more inclusive and accessible to people around the world, with EGU’s annual General Assembly EGU22 serving as a recent example. Postdoc researcher Jenny Turton tells us about atmospheric processes that affect the ice, through her work on the largest remaining floating glacier in the Arctic.
EGU’s Outreach Committee seeks new members by 12 June 2022 to promote the Earth, planetary, and space sciences among scientists, the public, and policymakers.
Applications are also open for EGU’s Science Journalism Fellowship and Public Engagement Grant, deadline for both is 17 June 2022!
