In my answer to the question "Mapping the moon: how to use the Lunar Reconnaissance Orbiter (LRO) image data?" I include a link to https://lrostk.gsfc.nasa.gov/preview.cgi which is a "real-time" viewer of LRO's position and what it is currently imaging. For example, it generates screens like that shown below.
But a few hours ago a comment there pointed out that the site seems to be down. That link returns the message:
File '/stream.mjpgpreview.cgi' not found
and https://lrostk.gsfc.nasa.gov/ returns
The server is too busy to serve your request at this time. The bandwidth being served (including your stream) is 1000800kbit/sec, and this exceeds the limit of 1000000kbit/sec.
The main "lunar" Goddard Spaceflight Center resources page is still fine though: https://lunar.gsfc.nasa.gov/resources.html
Is this unavailability a temporary condition?
The Where Is LRO page http://lroc.sese.asu.edu/about/whereislro is still active and generates the following map (click for full size):
