===Brief Initial Description===
Users and friends of the Jicamarca Radio Observatory will hold a
workshop to review activities from the past year and to prepare for
the next one. Important, new opportunities for research at Jicamarca
and elsewhere are afforded by the recent launch of the C/NOFS
satellite. Launched in April, the C/NOFS satellite occupies a 13
degrees inclination, 400 x 800 km orbit. The mission of the satellite
is to forecast ionospheric densities, irregularities and
scintillation.  Its instruments measure plasma parameters, electric &
magnetic fields (AC and DC), density fluctuations, and neutral winds
in situ. It also has a GPS receiver and an RF beacon. Ground-based
instruments and models, as well as space weather products are
integral parts of the mission. Full utilization of this instrumentation
for CEDAR science will require close integration with activities at
Jicamarca and other field sites.

Forecasting the properties of the equatorial ionosphere and the
irregularities within are objectives shared by C/NOFS and Jicamarca.
This workshop will address the forecast problem and the challenges it
entails. The launch of the satellite poses logistical as well as
scientific challenges. C/NOFS joins other long-term projects including
COSMIC and LISN requiring Jicamarca support, and the integration of
the various, related science goals and observing activities needs to
be discussed and planned. Support from Jicamarca will involve a number
of new observing modes and some relatively new hardware like the
AMISR-7, the SOUSY radar, the bistatic Jicamarca-Paracas link, and
SOFDI. Status reports regarding new radar modes and new ground-based
instrumentation at Jicamarca and other equatorial stations will
therefore accompany reports on C/NOFS satellite status.

The status of educational activities like the visiting scientist
program and the intern program at Jicamarca will also be
reviewed. Finally, science highlights in equatorial aeronomy from the
past year will be presented.

Individuals interested in making a short presentation should email the
session organizers.

===Workshop Description===

The first half of the workshop was decicated to the C/NOFS mission, and the
second half to new experiments, programs, and developments at Jicamarca. There
was naturally considerable overlap. The following presentations were made to the worhshop attendees, which numbered about 60. 

* Odile de la Beaujardiere - C/NOFS mission and status
* John Retterer - C/NOFS models and forecasting effort
* Don Hunton - PLP instrument status
* Rob Pfaff - VEFI instrument status
* Rod Heelis - CINDI / IVM instrument status
* Greg Earle - CINDI / NWM instrument status
* Paul Straus - CORISS instrument status
* Paul Bernhardt - CERTO instrument status

All the satellite instruments appear to be functioning normally, and calibration/ validation efforts are underway.

* Jorge Chau: Facility update, 150-km echoes
* John Meriwether: Recent results from Arequipa
* Marco Milla: ISR spectrum perpendicular to B: Magnetoionic effects
* Gerald Lehmacher: Radar cross-section, meteor radar, and HF radar at Jicamarca
* Meers Oppenheim: Large-scale simulations of FB turbulence
* Joe Huba: Three-dimensional modeling of ESF
* Dave Hysell: 2D simulations of collisional shear instability
* Fabiano Rodrigues: HF Doppler radar probing of ionospehric structure

Attention was drawn to the fact that the geomagnetic topology over Jicamarca
is changing rapidly and that it should be possible for the immediate future to
make highly accurate ISR drift measurements up to very high altitudes. New experimental features of the 150-km echoes suggesting the importance of velocity-space vs. configuration-space instabilities were also highlighted. Three efforts aimed at simulating gradient-driven plasma instabilities in the E and F regions in three dimensions were described. A number of new experimental efforts targeting mesospheric flows and irregularities including MST, MF, and meteor radar techniques were discussed. Finally, a very detailed investigation of magnetoionic effects on ISR spectral observations near perpendicular to B was presented.

The workshop concluded with an appeal from Jicamarca for proposals for 
observing time and experiments to support the C/NOFS satellite. This is
the first satellite with plasma experiments and open data availability
to fly over Jicamarca in a generation, and it can be exploited to advance
any number of scientific objectives in equatorial aeronomy. Proposals can
be formal or informal. Proposal pressure from the community will be 
helpful in securing more observing hours in upcoming years.
