Pulsing Red Light (orb?) stayed still then moved across the sky and faded away in Redwood Valley

At about 7:45pm I arrived at a house in Redwood Valley from Ukiah and was admiring how clear the night was and how many stars there were with a friend.   I didn’t notice it at first, but all of a sudden I saw a very large red/orange light.  
At first I thought maybe it was Mars, since I somewhat remember being able to see a faint red glow of a planet in Los Angeles – where I am from.  But I started thinking that it was too big to be a planet. My friend and I didn’t know what to make of it and both tried to take a photo – which didn’t work because all we had were our phones.   Then the bright star looking thing starting moving across the sky at a controlled speed that was fast, but not super fast, and pulsing slightly – so slightly I could barely tell it was even happening.  After about 15 seconds it stopped moving and began to fade until it was gone and I was back where I started admiring the sky.  My friend and I were at separate functions before this, we do not do drugs, we come from complete different backgrounds (SoCal and Massachusetts) and we saw the exact same thing.
