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 o ...[Read More]

Resolving the very fine details of the Sun in low frequency radio

Radio images of the Sun taken by a range of radio observatories at different frequencies.

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 di ...[Read More]

Not long until we all gather again virtually or in-person for the EGU 2022 General Assembly, and the Solar-Terrestrial physics (ST) Division’s Early-Career Scientists (ECS) Team is organising several events, which you might want to add to your personal programme!  SC4.12 – Meet the Experts: The Future of Solar–Terrestrial Sciences Thursday, 26 May, 17:00–18:00 CEST (UTC+2)Hybrid format: room -2.61 ...[Read More]

ST-ECS networking campfire event

ST-ECS networking campfire event

The EGU Solar–Terrestrial physics (ST) division’s early-career scientist (ECS) team is organising a so-called Campfire event to gather the community together before EGU22 and promote networking among ST-ECSs. The event will be held on Zoom and will take place on Friday 18 March 2022 at 15:00 CET, for a duration of one hour. We will make use of breakout rooms to facilitate discussions in smaller gr ...[Read More]

First year of Energetic Particle Measurements with EPD aboard Solar Orbiter

One year ago, the Energetic Particle Detector (EPD) aboard the European Space Agency’s (ESA’s) Sun observing spacecraft Solar Orbiter (SolO) was launched starting a long-awaited journey. SolO (Figure 1) will provide both in-situ and remote sensing measurements in the inner Heliosphere and EPD will contribute particularly to the latter ones. EPD consists of four sensors that share the s ...[Read More]

Meet the Experts: The future of solar terrestrial research

Every year at the EGU General Assembly renowned experts from the field of Solar-Terrestrial research get together to give inspirational talks and to meet with early career scientists. This year’s “Meet the Experts” session is focusing on the future of solar terrestrial research. To think of the future, we first have a look at the past, and more precisely on the knowledge acquired with over half a ...[Read More]

So… Who Cares about Switchbacks?

Explaining the Mysterious Plethora of Short Magnetic Field Reversals Observed by Parker Solar Probe and their Relation to the Origin of Solar Wind. In Switchbacks Explained: Super-Parker Fields – the Other Side of the Sub-Parker Spiral, N. A. Schwadron and D. J. McComas provide a simple geometric explanation for the source of “switchbacks” and associated large and one-sided transverse flows in the ...[Read More]

Tips on engaging outside of your echo chamber

In my previous blog, I highlighted that public engagement needs to go beyond traditional approaches such as lectures, since these tend to only attract audiences who are already highly interested in science. However, our science is relevant to (and funded by) everyone, so we have a duty to engage beyond simply this “scientific echo chamber”. But how do you even approach attempting this? It seems li ...[Read More]

Filmmakers get creative with the sounds of satellite data

One of the major motivations behind research into solar-terrestrial physics is the potential consequences of space weather on our technologically dependent society. Given this risk, recognised by many governments around the world, it is a little concerning that a sizable fraction of the public have never even heard of the term “space weather” – for example a recent public dialogue in the UK showed ...[Read More]

FOXSI: The NASA mission that combines rockets, flares, and X-rays

FOXSI: The NASA mission that combines rockets, flares, and X-rays

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 ...[Read More]
