GALEX Image: What's this?

https://www.legacysurvey.org//viewer/?ra=192.3069&dec=14.8295&layer=galex&zoom=13
Nothing visible in other surveys nor in Aladin lite Galex image

Hmm that looks weird. I suspect its an artifact, though I guess it could be some sort of weird UV-exclusive PN. The aladin lite version of galex doesnt actually cover this area, so thats why its not visible there.

I’m going with artifact, but thats just an educated guess.

Nearby there are clear artifact “ghost donut” images like at 193.2771, 15.0589 or at 193.2183, 14.9768
Our image is clearly evident in tile GI5_057007_NGC4710, but not present in GI6_001085_GUVICS08
