Maybe someone should ask from our only local expert on this subject, the self-professed scientist -Rocket Rohitha. Could be that he sent another satellite while we were asleep and the first or the second stage fell down in the sea near Oahu, Hawaii.
PS: Even though Unidentified, it doesn't imply this is of extra-terrestrial origin. The most possible explanation is the one I mentioned above. The first or the second stage of a rocket. Someone will acknowledge in due course.
