One minor critique, which is seen clearly in the NEOCP log. The first precovery observations that showed an interstellar orbit were submitted by Quanzhi Ye from the Zwicky Transient Facility (I41). Not S. Deen.

The elements have changed a bit since that original NEOCP plot was generated. You can make a new plot anytime here. In the "MPC #" box type 3I, then click "FROM MPC". Can change the view and save images.

Very fast NEOCP object discovered by our MAPS survey in Chile and confirmed a few hours later by me from France :-)
The asteroid of 4-11 m approached Earth at 0.22 lunar distance (84000 km).

That's a work-in-progress that I'm writing. I want to know at any given time what asteroids can I see in my telescope. This program currently is capable of pulling in all asteroids, only neas, neocp objects (which are usually too dim for me), deep sky, Sun and Moon.

#IMPACT UPCOMING: a small (1-2 meter) #asteroid discovered by Catalina will #harmlessly impact in the western Pacific today, nominally around 16:26 UTC (4 Sept). Object CAQTDL2 on the NEOCP. Will cause bright fireball and maybe some stones splashing into the ocean.

As the Moon brightens the night sky, once again #NEOWISE tracklets are on the NEOCP. Just remember the albedo and visual brightness are very uncertain until the first optical detection, so plan for ~2 mag fainter than the prediction.
