When: August 9-11, 2010

Where: HAO/NCAR (Center Green)

Solar Flares and Coronal Mass Ejections (CMEs) are believed to originate from the
explosive conversion of energy stored in a current-carrying magnetic field. The rapid
release of this energy is manifest as energetic particles, rapid heating of plasma in the
solar atmosphere, electromagnetic radiation that spans the range from radio frequencies
to gamma-ray emission, and the large-scale, episodic expulsion of mass from the solar
atmosphere into interplanetary space.

Dr. Richard C. Canfield has made major contributions to our understanding of Solar Flares
and CMEs over a long and productive scientific career. He developed diagnostics of the solar
atmosphere using non-LTE radiation transport techniques applied to solar flares, and similar
astrophysical environments such as QSO Emission-Line Clouds. He used these techniques to
make and interpret new measurements that contributed to our understanding of how the solar
atmosphere responds dynamically to rapid flare heating. He developed and used new
instrumentation to measure vector magnetic fields. These measurements led to new
understanding of the pre-flare energy storage as coronal currents and to the origin of the electric
currents and magnetic fields that ultimately power flares and CMEs. His study of eruptive
flares contributed significantly to the present understanding of the connections between CME-
driven events in the interplanetary medium and the structure and evolution of the underlying
solar magnetic fields.

To honor Dick Canfield's scientific achievements, we are organizing a
workshop to review progress in the areas of:

* radiation transport theory and diagnostics,

* flare and CME energy storage and release, and the ensuing

dynamics of the solar atmosphere,

* the measurement and analysis of vector magnetic fields

in the solar atmosphere,

* the connections between solar magnetic fields and disturbances

in the interplanetary medium

We have also requested and received approval for a special issue of Solar Physics,
that will be devoted to the topics covered by this workshop. Workshop participants
are invited to submit papers to the special issue. The submission deadline for papers
is anticipated to be in December 2010. Scientists interested in the topics covered by
the workshop, but unable to attend it, are also invited to submit papers. More details
will be provided at the meeting.

Meeting Schedule

Breakfast will be served from 8:00 to 9:00AM on each of the three days, and lunch
will be served from 12:00noon to 1:00PM each day. Talks and discussion will be from
9:00AM until 10:30AM, from 10:50AM until noon, from 1:00PM until 2:30PM,
and from 2:50PM until 5PM on each day. Coffee breaks will be from 10:30 until
10:50AM and from 2:30 until 2:50PM each day.

There will be a reception at 5:30PM on Monday August 9, and a dinner for
Dick Canfield on Tuesday at 6:00PM at Boulder Beer.

We anticipate between 4-6 invited talks during the meeting of roughly 45 minutes
duration, with the remainder of the talks being oral contributed talks lasting
15-20 minutes.
We also plan to have one extended topical discussion per day, lasting roughly one hour,
highlighting research areas of current interest, and also chosen to be areas where
Dick Canfield has made major contributions. Our tentative plans include one
discussion on the relationship between magnetic helicity and the occurrence of
solar flares, one discussion on the role of the chromosphere during solar flares,
and one discussion on the relationship between properties of interplanetary
magnetic clouds and magnetic features on the solar surface.


Participants will be responsible for making their own lodging arrangements.
A list of available hotels, and links to them, are shown at the left.


Participants need to register for the meeting in order to attend. Currently, the meeting
space is limited to 50 participants, so it is important to register promptly if you want
to attend. The registration deadline is July 4, 2010, and the registration fee will be $200.
Please fill out the registration information in the link at the left, and then click the "submit"
button. You will be linked to a webpage at UCAR that will process your payment by
