In 1983, I saw 11 Alterna on Juno but only one night did I see two on the same night. I think it was June, the night of the full moon. I saw the first one just north of bakers right at sun down and the other one about 13 miles north at about mid night. Never saw two in one night on Juno after that but I have seen multiples on the river rd more than once.
