After relocking, just before 03:00 (20:00), PI modes 18 & 26 started to ring up. It took many iterations to get the modes to start to come down. When they were coming down they would hit a point just above the 1 line, drop straight down, then bounce back up. For a while the bounce backs were getting smaller and smaller. However, after a several minutes, they both started to ring back up. After many more tweaks both modes started to come down. They were still dropping just before the 1 line, and then bouncing back up. The trend was downward and after about 20 minutes both modes disappeared into the noise.
