OF THE
TIMES
It felt like a group of waves, that hit one after the other. Some glass was broken in apartments, the furniture was shaken, but it was not a simple earthquake, and the sound was identical to a sonic boom and very very similar to this Russia meteor sound shockwave.
The weather was very cloudy, so I can't tell if there was any smoke or trace of anything. 15 minutes after the first wave there was another. It was less powerful, but it lasted longer, for about 5 minutes. After the bang, lights from the house and the TV turned themselves off and came back on after a few seconds.
No one knows what happened, but a lot of people heard and felt it, from the center of the city to the areas located some 50 or 75 km from the center. Unfortunately, I couldn't find any news about craters found or recordings of the event yet. There are some photos of shattered glass, and one local mall was affected, but officials either keep quiet or they answer it wasn't them.
The ice crystals in the cirrus clouds high aloft must be shaped like plates and the wind aloft must orient those crystals at just the right angle to act as prisms for the sunlight. Also, the sun must be at an elevation above the horizon of 58 degrees or greater, which only occurs in the late spring through early fall in the Pacific Northwest. The rest of the year, the sun never gets high enough in our sky.
