Standing out back i noticed what appeared to be a very small light at the end of a periscope-looking thing. the periscope (rod/pole) was maybe a foot high, looked to be silver and was seated in the dirt about 2 feet from the tree where i originally saw the domed light disappear into the crotch of a tree at ground level, and the being returning to the domed light that spotted me. this light - was extremely bright, but small - certainly less than an inch in diameter and was fixed ...In other words it did not move. it appeared to be a beacon or marker. i stood and observed it for approximately 5 minutes - being very still. i quietly went back inside to grab my camera - but when i returned it was gone. i hung around on my deck to see if it, or the being i'd seen some years ago would show itself, but could see or hear nothing. unlike my 1st experience with the being and the domed light some years ago i was very calm, not nervous and was careful to listen for any sound, notice any movement etc. this beacon has not been there since....
