OT Arc welding and electronics

Mike Shade

Having some work done on the observatory before monsoon hits.  The contractor needs to do some welding on the rails for the roll-off portion.  He will be using an arc welder but will be some 18 feet or so from any electronics.  He offered that this might be an issue for electronics.  I was planning on disconnecting and isolating cameras, control components for the scopes and computers like I do when monsoon hits with its terrible lightning storms.


Any thoughts on this or the potential dangers?  It is not feasible to bring equipment into the house, unplug isolate is all I can do.

Already, in the gathering dusk, a few of the stars are turning on their lights.

Vega, the brightest one, is now dropping towards the west.  Can it be half

a year since I watched her April rising in the east?  Low in the southwest

Antares blinks a sad farwell to fall...
