Greetings again,

I performed a similar conjunction search for the Hubble Space Telescope.
I noticed that Hubble was visited by DMSP B5D2-3 Deb D on March 18
at 17:34:22 and 18:22:53 UTC at ranges of 3.4 km and 7.5 km.

But tomorrow (Friday), HST will get a close-up view of STEP 2 Pegasus Deb =
HZ
(#24174).  Conjunction is at 17:02:00.6 UT at a current predicted range =
of only
500 meters.  (The orbits miss each other by 400 meters, so there's no =
danger
of impact.)  The Pegasus debris will be below Hubble, and both will be =
sunlit.  Conjunction occurs above Mecca, Saudi Arabia.
