Thought I was watching a helicopter coming from the NW but while watching it it wasn’t moving after all just kept watching it pulsating red then it just faded away. I had the sense of anxiety really bad ran inside and told my husband and he said cool. Cause I saw one over the San Gabriel mtns a few years Back so he knows I saw it. I was in my kitchen looking out towards the west and saw it to the right so that would be NW. I didn’t lose sight of it it just faded out to nothing.
