One day go to your field site, short across the sparkgap. Put a current meter or resistor with voltmeter across it, across the sparkgap, remove the short. Now you can spend your usual amount of time in your usual position - you could watch the current changing with time. With no high voltage (since the resistor or ammeter 'shorts' the collector to earth) see if you still get a tan/rash. Boring but objective.

Or shield the gap (the easy way) or the windows (if you like that idea better) and see if the effect persists. Al foil is opaque to UV and Visible radiation. Lead foil (or shot in bags) will stop Xrays. Or try sunscreen... BTW, if you go out in the sun do you usually burn or tan?

Each summer, I get a fairly dark tan from being outside in the hot Florida sun. But, I've also been lobsterized several times, mainly as a kid watersking all day without thought to how much time I'd been in the sun. I've experienced sunburn... this sensation is admittedly similar... but is even better described as a 'glowing sensation' as described by other people experiencing something similar in the Niels Jonassen article referencing static induced redness or rash. Who knows... could the sunlight or uv somehow be entering my RV in some unconventional way, in strong enough qty to burn one side of my face? Maybe... but not likely. If someone pressed me to make an educated guess... I'd have to say the static induced theory seems most likely. I have 400 collectors designed to collect and direct HV to a spark gap a few inches from my face. Probably not the best arrangement... but my RV is very small. CM
