At least the arc has burnt the cobwebs ;-)

Hope the stainless steel tubing (with the laboratory clamps) in the background are not the intake of an air-pollution monitor. If it was, it may ring an alarm due to a sudden NOx increase..

Nice pictures with the Nikon D700 !

Seems i need some improvements on the spark gap of my LF antenna. Depending on the humidity and wind there is some arcing during the transmissions. These look very fascinating i find. Anyway i have to add a spherical electrode there and increase the gap distance, especially for VLF ;-)

A working colleague of me is a (semi) proffessional photographer (hobby) and i asked him to take some nice pictures. He has an excellent equipment i find but he means he should have taken a different lens for these pictures. Anyway, i really like them. When arcing at the ends of a LF antenna is discussed, sometimes a picture can help a newcomer what is meant. Here are some more examples, in high resolution (abt. 3 MB each)
