We saw 3 glowing oval objects in the sky last night.

Jerry and I both saw 3 orb like objects in the sky last night.  They were glowing red/orange bright light.  They were very low. About 500-800 ft in the sky.  They were in a straight line.  Then they started moving slowly towards the south.  As they moved forward one paused in front of our house and then went west and disappeared.  The other two continued south slowly and paused in our side yard airspace then slowly dimmed and disappeared.   I don’t know how to explain what they could have been.  The dogs woke us up around 12:45am.  It went on until about 12:59 am.  It was amazing.  One of the orbs sat right outside our balcony and just dissolved away.  They were very large and glowing.  I could hear a faint humming sound.
