SOHO-23: Understanding a Peculiar Solar Minimum
(Issue March 15, 2009)

The SOHO Science Working Team has scheduled the twenty third in the series of successful SOHO workshops to focus on the topic of the unusual minimum of solar activity that persisted throughout 2007 and 2008. SOHO-23 is scheduled for 21-25 September 2009, at the Asticou Inn in Northeast Harbor, Maine.

The SOHO-23 meeting will cover all aspects of solar and heliospheric science that deal with solar cycle variability and the evolution of solar activity on time scales from seconds to decades. The “new millennium solar minimum ” of 2007-2009 has contained some distinct surprises, including a delayed onset of Solar Cycle 24, the absence of a classical quiescent equatorial streamer belt, and anomalously low heliospheric magnetic fields, densities, and temperatures. The scientific sessions for SOHO-23 will cover topics that include the solar dynamo, magnetic flux emergence and the “magnetic carpet,” coronal and heliospheric magnetic fields, irradiance, coronal heating and solar wind acceleration, in-situ heliospheric plasma properties linked to the Sun, and the testing of solar cycle predictions.

The full first announcement for SOHO-23 is on the meeting web site at www.soho23.org. Other details, including deadlines, a pre-registration form, and information about registration, abstract submission, and local accommodations, will appear as they become available.
