I see the Zwicky Transient Facility spotted it 9 days ago but only reported it on TNS today.

There are not so many unique amateur discoveries these days with all the robotic surveys. I am starting to see the same with my spectroscopic confirmations as more dedicated pro spectroscopic capability comes on line. Initially when I started in 2016, most of mine were stand alone confirmations but now most of them eventually get a second pro followup spectrum.
