Shooting the comet and waiting for the ISS to pass nearby (that happened a few minutes later) and caught this intense circular bolt and double ground strike. The lightning was about 20 miles distant so no worries for me shooting from an exposed rock outcrop.

Nikon Z6, Nikkor Z 24-70mm F/4 with didymium light filter.

Some color correction and dehaze due to light pollution and the comet being very low on the horizon. Boosted exposure as I was shooting underexposed at 1600 ISO to allow for longer shots to catch the lightning.
