No. If a shadow passed over you, then the object would have had
to be large enough to eclipse a large part of the sun. Recall that the
sun is half a degree or close enough to a hundredth of a radian. If
you saw nothing, no contrail, it would need to be well outside of the
atmosphere, perhaps a good 200 km up, in which case it would need
to be 2 km across. Anything that big would set off radar all over the
globe.
When you were working outside, could it be you were working
close to the ground, having had no food for some time and stood
up suddenly, causing your eyes to do something funny? Ive done
that. spike
