ST-ECS Networking Campfire: How to select collaborators or your future research group?

Eleanna Asvestari March 2, 2023

Whether you are about to start working on your thesis, or you are ready to join a new research group, deciding which PI and which group to join is not something to be taken lightly. One first has to go through the process of understanding their goals and wishes, what the PI/group can offer, and whether they will fit in. The Early Career Scientists (ECS) team of the Solar-Terrestrial (ST) division ...[Read More]

The impacts of space weather on the mid-latitude upper atmosphere

authored by Daniel Billett, edited by Eleanna Asvestari January 27, 2023

The upper atmosphere of Earth is constantly being impacted by the flow of charged particles being released from the sun. This flow (the solar wind) carries with it a magnetic field which distorts and reshapes that of Earth, ultimately resulting in a large amount of electromagnetic space weather energy being channelled into the polar regions. One of the most frequently observed outcomes of this pro ...[Read More]

Meet the Early Career Scientists team of our division!

authored by Liliana Macotela, edited by Eleanna Asvestari January 13, 2023

Hi, this is your ST-ECS team. We are a group of Early Career Scientists (ECSs) of the Solar-Terrestrial (ST) division, and we enjoy organizing events and activities with and for ST-ECS, both during the EGU General Assembly and throughout the year. Our aim is to increase the visibility of ECSs and provide you with opportunities for networking. Currently the team is formed by: Dr. Maxime Grandin Max ...[Read More]

Events organised by the ST Early-Career Scientist (ECS) Team during EGU22: We would like your feedback!

authored by Maxime Grandin, edited by Eleanna Asvestari & Luke Barnard June 2, 2022

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]

Reflection after the investigation of the direct First Parker Solar Probe Observation of the Interaction of Two Successive ICMEs

authored by Teresa Nieves-Chinchilla, Nathalia Alzate, Hebe Cremades, and Laura Rodríguez-García, edited by Luke Barnard May 31, 2022

In Heliophysics there is a scarcity of in-situ buoys that allows us to monitor and track the solar wind changes in our Sun’s atmosphere, the heliosphere. NASA’s Parker Solar Probe (PSP) mission is one of those buoys that, together with Solar Orbiter (SolO, ESA/NASA Collaboration), is bringing a breath of fresh air in the effort to fully characterize the solar wind and study the evolution of the em ...[Read More]

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

authored by Peijin Zhang, edited by Luke Barnard May 24, 2022

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]

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 ...[Read More]

ST-ECS networking campfire event

authored by Maxime Grandin, edited by Luke Barnard March 1, 2022

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]

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]
