IAGA SYMPOSIUM IS 2.15/3.11:  Interhemispheric Contrasts in Substorm 
			      Signatures

Convenor: J.C. Samson
Co-convenor:  J.R. Dudeney

This symposium encompasses studies on the experimental and  
theoretical evaluation of significant interhemispherical contrasts in  
the signatures of substorms.  These studies should aim at providing  
critical tests of competing substorm theories.

ABSTRACT DEADLINE is February 1, 1995.  The original and two (2)  
copies of your abstract should be sent to:

From:  J.C. Samson (samson at space.ualberta.ca)

IAGA SYMPOSIUM S 3.7: Nonlinear and Kinetic Effects in ULF Waves

Convenor: J.C. Samson
Co-convenor:  R.L. Lysak

This symposium will focus on studies of the nonlinear evolution of  
ULF plasma waves and kinetic effects in the interact of ULF waves  
with the plasma population.  The studies include the lowest frequency  
magnetohydrodynamic waves, up to and including waves at the ion  
cyclotron frequency.  Submission of theoretical computatonal and  
experimental studies are encouraged.
