S-RAMP Symposium on Tail Plasma Flows and Ionospheric Consequences
------------------------------------------------------------------
From: Vassilis Angelopoulos, Space Sci. Lab., UCB (vassilis at ssl.berkeley.edu)
  and Tsugunobu Nagai, Tokyo Inst. of Technology (nagai at geo.titech.ac.jp)

First Announcement and call for papers for the 
1st S-RAMP symposium on "Tail plasma flows and ionospheric consequences"
October 2-6, 2000, Sapporo, Japan.

Observations of fast, geoeffective magnetotail flows during the course
of auroral activations deserve special attention. Correlative measurements
between ISTP platforms which are greatly aided by the simultaneous availability
of high quality ground observables are well on their way to improving our
understanding of the behavior of the coupled magnetospheric-ionospheric system.
Such coupling is present under a variety of active conditions, including
pseudobreakups, small or large substorms and convection bays. On the
other hand the behavior of the magnetosphere under conditions when
an ionospheric two-cell convection pattern is established, is much
different. The flow state under such conditions deserves attention from the
point of view of whether steady-state, slow convection is at all present
and in what form. We solicit theoretical, observational and modeling
papers pertaining to the problem of ionospheric signatures and control
of magnetotail flows.

Items expected to be reported on include:
 * fast tail flows and their association with geomagnetic activity
  (pseudobreakups, small substorms, convection bays or large substorms)
 * fast flows as a unified description of the tail activity
 * modeling of currents and their ionospheric effects in localized energy surges
 * conjunctions of ground, low altitude and equatorial magnetotail satellites
 * large scale convection observed in the ionosphere and its association with
   average equatorial flow pattern
 * intense, localized ionospheric flows and their magnetospheric counterpart
 * north-south arcs and their association with magnetospheric fast flows

** DEADLINE for submission of papers is: March 15, 2000 **

S-RAMP stands for "STEP-Results Applications and Modeling Phase". The
first S-RAMP conference in Sapporo represents the first meeting on
the analysis of the STEP (Solar-Terrestrial Energy Program) datasets.
The S-RAMP program is a five-year effort (1998-2002)
to optimize the analysis of STEP data, and is sponsored by SCOSTEP.
