EQ reported by Terramon BEFORE it actually arrived? I noticed asc, imc doing eq band stuff before even USGS listed it. Attached plots show pitch and yaw asc trends from 10-15 (left side of each screen) minutes before and 10minutes during. Look at the ITMY STS blrms in the lower left of each image to get a feel for what the ground was doing.
