Hi all,

Sam Deen, in the MPML (Minor Planet Mailing List) have just reported a
transit that seems a satellite for me, although he thinks It could be a NEO

I copy paste his email asking for your opinion

*I noticed that in a recent solar image taken by GOES-16 there is a very
visible streak across the solar disk and surrounding Corona:*

*This is very strange for quite a few reasons:*
*1: GOES-16 is in geosynchronous orbit*
*2: this image was taken while GOES-16 was over Earth's day-side, meaning
that it was looking FURTHER than geosynchronous orbit*
*3: the streak clearly appears quite strong, suggesting a rather large and
slow-moving object transited across the sun.*

*This seems to have all the features of a near-earth asteroid photobombing
the Sun on a near-Earth approach. Even the apparent brightness fluctuation
doesn't seem to indicate a satellite: you can see the apparent 'largest'
parts of the streak are where the Sun is dimmest, while the 'thinnest' are
where the Sun is brightest. The actual trail is quite constant, but the
brightness it silhouettes varies.*

*Can anyone with more familiarity with the GOES-16 satellite identify what
exactly this object is? Unfortunately the released image is highly
contrast-enhanced so it's hard to tell anything concrete about the streak.*

*~Sam*

Do you think a Sat is possible at this orbit with this kind of path, or is
it more like a natural object?

Sincerely,
