Hello,

This is the observation i made last night from my observatory. I have
seen this kind of cloud displacing along X1 theorical trajectory at
least three times in last two weeks. Could be any kind of reflection or
artifact, but at least in two of my sequences it is clear.

Perhaps this is what J.J. Gonzalez has seen.
