What is this?

Hi Wolfgang,

See what you mean.  If you look closely it seems to me that each is also  associated with a short red line  on the opposite side (relative to the satellite trail)  of the two green-circled bright spots  which (based upon the image scale v height scale that you estimated) may be within 30m?  

I wonder if this is part of an array of identical satellites  moving in synchrony and you just happened to have caught two of them with each having one part (solar panel?) more reflective ?  However, if so they do seem to be moving too slowly ?/ impossibly high given so little angular movement in 3 min ?

PS Forgot that your scope is tracking so maybe geostationary satellites?

PPS and had also forgot that the DEC of the Lion is about +55 deg!   So maybe not GEOSAT -- or they are spy satellites in geosynch rather than equatorial orbits :-)

Hi Tim, well spotted indeed:

apologies for the unsharp 400% image but the red lines you spotted are hard to see even in the 100% view above. And yes, 22 - 32 m distance for the typical satellite height, so most likely some solar panel. I have to check the exact time and whether a solar reflection could be possible in this position at that time.

Thank you for your support and clear skies!
Wolfgang

Addendum:
Very high flying planes look like this one (passing the coathanger):

upper short streak is a high flying plane, lower long streak a satellite.

Clear skies

Here is what a Federation X-Wing Fighter looks like passing through a frame

Christoph Lichtblau:
This is clearly the becon light pattern of an airplane. I had several of them on my subs. In addition you can see the red position light on the wing edge

Does this refer to the original picture or the X wing  fighter which looks pretty nailed on to me?

I don't think at all that it's aliens. But what still puzzles me about the airplane suggestion:
How do you explain that the image of the light source is point-like? For a point like image the airplane has to fly at a low angular velocity (i.e. reasonably high in the sky). But if this is the case, then why are there only two light points in a 3 minute sub? The overall angle of the path of the light source spans about 1.4 degrees, these 1.4 degrees are passed with only two "flashes". As I already pointed out I see a lot of planes in my images in each session. I so far never had a pattern like this one and I find it hard to corelate the image with the high frequency of a beacon light. In addition, there remains the question why do we see the beacon light but not the mandatory position lights on the tips of the wings left and right of it? Admittedly, at some height of the plane these lights merge into one but at that point you just get a light trail as depicted in the coathanger image above.

I'm happy to believe the airplane hypothesis if someone can answer these questions convincingly.
