Lots of info there for those interested in astronomy.
Also satellite data. My hobby, amateur radio (my call AI3N), and there is a complete list of ham satellites, now numbering well over 100. That was a surprise, so many in orbit right now. If you have a receiver tuned to the right frequency you can hear talking going on between two hams on Earth using a ham sat for relay. Frequencies either in the 440 to 450 Mhz or 144 to 148 Mhz downlink frequencies.
I guess not many people care about that but there is a lot of info there.
