No. 482, “High-resolution observational analysis of flare ribbon fine structures,” by Jonas THOEN FABER. Spatially periodic but unresolved emission kernels.
No. 483, "Spatial and Spectral Evolution of Microwave and X-Ray Sources During the Limb Flare SOL2023-02-05,” by Yulia SHAMSUTDINOVA. Rare microwave imaging spectroscopy of a hot-onset precursor event.
No. 484, "Unveiling CME Dynamics: Rare Rotations of CMEs in the Heliosphere,” by Sandeep KUMAR and Nandita SRIVASTAVA. CMEs usually do not show additional rotation as they move though the heliosphere, but there are interesing cases.
As always, we welcome new items and encourage opinion pieces and news items as well as descriptions of new discoveries.
Just email Hugh Hudson with a page of text and 2-3 nice figures.

Dear All,
I'm forwarding an announcement of new textbook from Dr. Markus Aschwanden.
Best,
Keiji

It is my pleasure to announce the new textbook:
Power Laws in Astrophysics. Self-Organized Criticality Systems
by Markus Aschwanden
published by Cambridge University Press, Cambridge: UK (2025)
Research applications of complex systems and nonlinear physics
are rapidly expanding across various scientific disciplines.

[View More]A common theme among them is the concept of “self-organized
criticality systems,” which this volume presents in detail for
observed astrophysical phenomena, such as solar flares, coronal
mass ejections, solar energetic particles, solar wind, stellar
flares, magneto-spheric events, planetary systems, and galactic
and black-hole systems. The author explores fundamental
questions: Why do power laws, the hallmarks of self-organized
criticality, exist? What power law index is predicted for each
astrophysical phenomenon? Which size distributions have
universality? What can waiting time distributions tell us about
random processes? This is the first monograph that tests
comprehensively astrophysical observations of self-organized
criticality systems for students, postdocs, and researchers.
A highlight is a paradigm shift from microscopic concepts,
such as the traditional cellular automaton algorithms, to
macroscopic concepts formulated in terms of physical scaling
laws.
MARKUS ASCHWANDEN studied observations and theoretical models
of self-organized criticality systems over the last 40 years
as a researcher at Lockheed Martin Solar and Astrophysics
Laboratory, analyzing space data from many NASA missions.
He has organized self-organized criticality-dedicated
workshops at Inter-national Swiss Space Institute Bern and
co-organized a workshop at Leiden University. He served as
Editor of Space Science Reviews and is a member of the
American Geophysical Union, the American Astronomical
Society’s Solar Physics Division, and the Committee of
European Solar Radio Astronomers.
