No. 262, “Fine Structure in Flare Soft X-ray Light Curves,” by Brian Dennis and Kim Tolbert: A tool that we’ve had since 1976 now gives us surprisingly precise new information.

No. 261, “Photospheric Electric Fields and Energy Fluxes in the Eruptive Active Region NOAA 11158,” by Maria Kazachenko. Flares need magnetic energy; we can now measure its arrival as Poynting flux across the solar photosphere.

No. 260, “RHESSI and General Relativity,” by Bill Thompson and Hugh Hudson. General-relativistic corrections to RHESSI source positions.

listing the current series, 2008-present, and

for the original series, 2005-2008.

We publish these at roughly two-week intervals and welcome contributions,
which should be related, at least loosely, to RHESSI science.
