You might have.  The moon passes through the earth's shadow during a lunar
eclipse. I don't know if this means the umbra or not, however I do know
that since red light is bent most and violet light is bent least about the
earth, the red light (and lesser EM radiation) is able still to touch the
moon and reflect back to us.  So you can know for certain it is a lunar
eclipse when you see that the moon is a very dim red.
