At noon approximate 2hours NATO 01 draws circles in the sky.
I like to see your observations.
It is a standard holding pattern.
IFR pilots do them all of the time.
The military would probably use it if they wanted to loiter at or monitor a particular location.
Some time ago they were making perfect circles for a couple of ours directly overhead my location.
The type in skyview even says E3TF (Boeing E-3 Sentry - Wikipedia)
So that’s what one of these planes does, they are airborn radar.
It was bound to happen. You setup your own ADS-B station, and this is the result. They send NATO after you.
NATO AWACS (c/s NATO01) used the so-called NG4-Orbit.
Look at ENR 6 Charts, page 8 (E-3A Orbit Areas).
On page 7 you’ll find the AARs (Air Refuelling Anchors); AAR “ANGIE” is located in the same area as NG4.

Probably a fighter jet (Typhoon) doing it’s thing…
Ah, that explains why that many C17 arrived all over this morning on Ramstein AFB.
