Mate this gave me chills reading it. The hovering thing is what gets me - moving objects have some kind of explanation most of the time but something just sitting there, stationary, that's harder to dismiss.
Did it make any sound at all? That detail always stands out in the credible reports. Also what time roughly? There's a lot of documented activity in rural Gloucestershire (I'm local) and the cornfield setting is interesting because there's theories about UAPs being drawn to agricultural areas, electromagnetic fields in the soil, that kind of thing.
What did it look like when it eventually moved off? Did it accelerate or just sort of fade? Really want to hear more of the details because your description of the light quality sounds different from the usual drone stuff people misidentify.
Others seen anything similar recently? Feel like there's been a spike in reports this year.
