Not quite sure where this fits but I will put it here
There have been some interesting GCN (Gamma ray Coordinates Network) circulars generated this afternoon. It seems there may be gamma, optical and neutrino detections coincident with a Gravitational Wave Event (S190728q) detected earlier today. All very preliminary but I thought it might be cool to image the possible optical counterpart if you have clear skies (at mag 19.8 it is too faint for me for a spectrum unfortunately)
The optical transient is AT2019lvs, well placed at 21:45:34.900 +20:41:26.10

The GCN circulars can be found here

and the most relevant ones are
25187, 25189, 25192, 25197, 25199, 21201
