Trouble spotting NOAA 4 (7529, 74-089 A)

I've been trying to add NOAA 4 (7529, 74-089 A) to my list of observed
satellites for a month or so now;  Nothing observed out of about 7 tries.
If the RCS is really around 8.4 sq. meters, as I believe it is, I
don't understand why I haven't been able to pick it up with my 4.5
in. telescope at 40x.  I know that it is in a sun synchronous orbit,
hugging the terminator, so that prevents me from seeing it in totally
dark skies, and I'll never see it front-lit.  Still, the orbit is
high enough to allow me to see it in reasonably dark skies.  I've
seen much smaller objects under worse lighting and distance situations.

Has anyone seen NOAA 4?  It isn't in the Molczan file.  I got this
from OIG today...
