I wrote the chief counsel's office about fifteen years ago on this
issue of logging "black hole time" after a long dispute about it on
AVSIG.
They sent me a copy of the above - supporting my position that the
criterion was "solely by reference to instruments" as opposed to "IMC"
for the logging of instrument time.

Reminds me of a time flying VFR over the top at night and the
controller asking my flight visibility. I said about 250,000 miles.
After the silence, I said that all I could see was the moon.

Moonless night over a cloud deck.

One that got my screwed up was fying along on top of a cloud deck that was
pitched at about a 30 degree angle -- pretty hard to override the
inclination to assume a flat deck below you.
