On a dark background, the Moon nearly covers the Sun, leaving only a bright crescent visible on the left-hand side. The Sun's surface looks active, with bright yellow glowing loops sticking out from it. The Sun emits a yellow-orange glow that extends around the dark Moon, and faintly lights up the Moon's left side. Craters are faintly visible on the Moon's surface. The top right has an ESA logo, and the bottom left has text reading “solar eclipse; coming to Europe.

What will the solar corona look like during the 12th August solar eclipse? The LASCO-C2 coronagraph aboard SOHO @science.esa.int gives us a sneak peek! As the Sun rotates roughly every 27 days, we can look at previous solar rotations to anticipate the corona’s structure. (1/5)

How does the evolution of solar wind sources modulate the effective rotation of the solar corona? Updated visualisation of our work from 2023: www.aanda.org/articles/aa/... At minimum, solar wind emerges from slowly rotating poles. Increased activity drives sources to latitudes with faster rotation.

Are you (or do you know of) an undergrad with an interest in solar physics? Check out the Leiden/ESA Astrophysics Program for Summer Students (LEAPS 2026). Myself, Andy To and Henrik Eklund invite you to come work with us at ESTEC on "Catching the Solar Wind in Action". leaps.strw.leidenuniv.nl#none
leaps.strw.leidenuniv.nl
LEAPS
LEAPS is an opportunity for students with an interest in astronomy and astrophysics to perform a 10 week summer research project in collaboration with a research scientist from Leiden Observatory or ESA/ESTEC. The program is open to all students not currently engaged in a Ph.D. program (please see the full eligibility criteria) We would like to use LEAPS as an opportunity to increase the diversity of researchers in Astronomy as we understand that successful science is supported by this. Students are selected for the program based on their academic achievements and research potential. Each applicant has the opportunity to choose up to two projects of interest, and they are selected by project advisors based on what they indicate their scientific interests and experience to be. Research at Leiden Observatory and ESA/ESTEC takes place on a diverse array of topics (see below for LEAPS 2026 projects), and student projects will likely consist of anything from the analysis of data from world-class telescopes, to large computer simulations, to hands-on work in the astrochemistry laboratories.
