Vol. 3, No. 8                                              Sep 16, 1996



			  Final Announcement


   "QPS: A Rosetta Stone for Understanding Large-Scale MHD Activity
		      near the Galactic Center?"

    A Specialized Mini-Workshop at UCLA on September 19 & 20, 1996
______________________________________________________________________

QPS is the Quintuplet(AFGL2004)/Pistol(G0.15-0.05)/Sickle(G0.18-0.04) 
complex located at the intersection of the Radio Arc with the Galactic 
plane. The workshop will focus on four areas:
 
1) the nature of the stars in the Quintuplet, and their winds, 
2) the physical conditions in the HII regions and in the neighboring 
   molecular clouds, and the constraints they pose on the ionization 
   mechanism and the source of ionization, 
3) the evidence for magnetic fields and the constraints on the magnetic 
   field geometry, both inside and outside of the dense clouds there, and 
4) the mechanisms for generating the nonthermal radio filaments of the Arc.

When and Where

The meeting will take place in the Sequoia Room of the UCLA Faculty Center,
located on Circle Drive East, near the Eastern edge of campus, from 
8:30 to ~5 on Thursday, September 19.  At the present time, we anticipate 
that the talks 
and discussion will continue through Friday morning, September 20.  

Getting to UCLA from the airport:

North on 405 freeway (about 7 miles)
East (right turn) on Sunset Boulevard (~1 mile)
South (right turn) on Hilgard Avenue (~0.5 miles)
West (right turn) into campus at Westholme

The parking booth where the $5 daily permit can be purchased
is then on your right, close to the intersection of
Hilgard and Westholme.  It is adjacent to the faculty center.
 
Park in parking structure #2. After parking, proceed North from
the parking structure to the Faculty Center (about 500 feet 
away).

Accomodations

Those who have not already arranged their accomodations should quickly try
to get a hotel in Westwood.  Laurie Liles (liles@bonnie.astro.ucla.edu)
can assist with reservations.
