Looks like the trouble report did not go out via email. Here’s the text, as found in the TR archive:<div class=""><br class=""></div><div class=""><pre style="word-wrap: break-word; white-space: pre-wrap;" class="">Problem(s) Encountered:
The RA drive made some squealing noises. These were louder and
shorter in duration than when the brakes aren't quite released.
Noticed that it only happened in an East-to-West direction and
when the telescope was slewing. Didn't lose any time over it but
thought it was worth mentioning.
I did lose time over a computer glitch. Prospero seemed to not
process an image I took. This was proceeded by every task on the
workstation failing to process. I couldn't close windows or
perform any commands in a terminal window. Ended up power cycling
the workstation, hiltner, and the IC computer before getting back
to observing.
