**CHIP PROBLEM**: Tue Jul  6 21:33:44 GMT 1999
Removed CHIP filter to inspect it on the workbench.  Found residual
smudges on the rear window and two bubbles or chips on the corners 
of some og the internal elements.  There was a larger canine-footprint
shaped bubble on one edge on an internal element that appeared to
invert the contrast.  There was a hairline across one edge of an internal
element.  I cleaned away the window smudge as best as I could.  David and
Kim decided we should try squeezing the hairline out--turned out to be 
a separation air bubble.  Tried squeezing the opposite edge first with
low torque on the screws on the front surface of the mount.  This did 
not work.  Deduced that the air wedge needed to be squeezed together 
so I gently squeezed on the bubble side and the bubble edged its way out.
The canine-footprint bubble enlarged slightly even though it was on the
same side as the large bubble.  It also changed shape slightly.  The other two 
bubbles/chips did not change.  We decided to resolve the large bubble 
first so I re-installed the filter.  Once the filter gets back on 
temperature and we can observe the sun, we will determine how much
improvement the fix made.  If there is still some residual  degradation,
we can then go after the other smaller bubble.
