black trail over the moon between 5h10 5h13 pm

hi, i would like to see if somebody can confirm an observation this
evening,
a black trail, smoke alike, appearing from the south of the moon,
crossing the disk to the left upper side, floating approximately 30
secconds, then going to the left and disepearing. I had fortunately
my 24*36 loaded with BW 3200 asa and took two shots of it. Others
drivers on highway slowed the cars.
I'lll devellop the film in 400 asa. I'll post the results soon.
location 49 20 34 06 03 03 17h10-17h30, duration 30-45 seconds
no clouds, no smoke trails from planes, no chimneys, temp 13 °

Thanks for your reports, it could be useful to signal them on these
urls and mails
