Orange circle (Like a super large sun at night) twice the size of a full moon.While I was standing outside letting my dogs do to the bathroom a small orange light appeared over the mountains northwest of Kalispell (Near were the sun is currently setting). At first I thought it was a plane coming through the clouds with its lights on. But soon after noticing it the light become larger and larger until it appeared to be twice the size of a full moon through partial cloud cover and then stopped growing. At first I wasn't sure what to think of it so I ran inside and grabbed my significant other. I pointed out what I was seeing and she told me that maybe it was the moon. I told her there was no way the moon was that far northwest at the current time (11:30ish PM). I proceeded to go back inside grab my phone to confirm using Google Sky Map the current location of the moon as it was cloudy outside and we couldn't see the moon. We then got on the computer and looked up luner cycles to get further clarification on the moons current location. I went back outside to take a photograph and it was gone. I then ran back inside and told my significant other it was gone and we both stood outside in disbelief... I should have taken a picture as soon as I noticed it... I dont know what I was thinking. My first confirmed sighting of something odd and I was more in shock and trying to disprove what I was seeing I guess. I won't let that happen again and will be spending more time looking up. The best way I can describe it was it glowed like the color of sun but twice as large... partially behind cloud cover. Blew my mind.
