Satellites, well, that is what we thought too! But experts say it can't be satellites for several reasons, 1. On average those lights fly too fast (60 sec. from horizon to horizon and sometimes (much) faster), 2. the light they emit is emitted, not reflected, 3. Satellites are visible 1 hour after sunset and 1 hour before sunrise (all info by a professor in 'astral bodies') 4. One Sunday night in July we counted 27 'flying lights' between midnight and 4 AM, besides improbable statistics, at those hours satellites are simply not visible and certainly not as bright as those flying lights are, 5. What may probably be not clear from the pictures, is that not all 'flying lights' follow straight lines, some change direction, some change velocity, some switch its light on/off, some 'zigzag' to a hold, do a couple of 'slow but very bright blinks' and then fly on, or on-the-spot just fade into thin air in about 10 sec. and many variations of this totally weird behavioral...
In addition to the 'weird-factor', while sky-watching with the nightly temperatures declining, so does the amount of 'flying lights in the sky' with last night, clear and dark skies and freezing a bit, we hit the all-time low of 0 (zero) lights seen fly by.
#wxsatuser, the local (Utrecht Netherlands) date and time are in the photo's, aren't they?
#ourobouros, thanks as well and what do you mean by 'A plate solve of the first image...'?
Hopefully and if, those flying lights return in reasonable amounts coming Spring / Summer You Stargazers Loungers will be the very First to Know!! and of course are All very Welcome to come and See for Yourselves!! (I am very sure too, that I would never ever believe this, but every word is true and more...)
keep you updated!
Cheers!
