N is at the top, E is to your L.

The wow signal came from one of those two red ovals (the exact location is uncertain, due to ambiguity of the receiving antenna). The ovals are approximately 3 minutes of RA (time) apart, and 40' of Dec (arc) tall.

Both ovals would fit easily in a box 60' (one degree of arc) square centered at Dec 26d 57' S, RA = 19h 27m. Remember, the full moon is 30' of arc in diameter.

The contrail runs in a roughly 110deg (just S of E) direction along the -27d Declination line from about RA 19h 30 to 19h 24m. I.e., it cuts right through both those little red ovals.

Does this mean anything? Probably not, but it still got my attention.
