What kind of trail is this?


Recommended Posts

It is definitely an aircraft trail.

You have the port and starboard navigation lights with a white strobe light, (hence the gap in between), on the wingtips. The yellow one in the middle is the anti-collision light; (top and underside of the fuselage); (they are/appear as red or white strobe light at ground level), and are used when an aircraft is in the aircraft maneuvering area or on a gate/stand of an airfield prior to push-back, etc; so that ground staff are made aware that the aircraft engine(s) are due to startup or are running; or when the aircraft is in flight.

I’m used to having trails in my images but this one seems particularly odd with the short red and yellow lines in the middle! Anybody know what it is?

Just wanted to ask what are you imagining? Looks nebulous.

Noticed that SpaceX had navigation lights, can't be a lot to bump into but I suppose it's an indication of orientation. 

In a nut shell... yes!

It does happen and sometimes gets reported. Just things like tools and other small FOD; (foreign object debris); cause a bigger dent or headache for those onboard a manned spacecraft/space-station or those in the flight control centre.

Ah brilliant thanks so much! I knew it would be either plane or satellite I just hadn’t had a trail look that strange before.

You are correct. IC1318 Butterfly Nebula, the bright star at the top is Sadr 🙂
