show that this storm will keep its main Bz > 0 field and its total field will decline, resulting in a West-North-East (WNE) flux rope. At the end there should be an interval Bz < 0 (=more aurora!)

A fast coronal mass ejection from the Sun has arrived at Earth! If you have clear skies tonight, you might be lucky enough to see some aurora. It’s cloudy where I am so send photos!

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
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.

The success of the UK space sector, and the role that the UK Space Agency plays in this, requires proper resourcing. Something the government must still commit to when the UKSA is absorbed by the Department for Science, Innovation and Technology next year.
