Hubble Plateaus

In times past we have lovingly tracked the proposal frenzy as the near annual Hubble Space Telescope proposal deadline approaches.

As was noted by Julianne several years ago, and confirmed over the last half dozen cycles, the shape of the curve of number of submitted proposals as a function of time until the deadline is nearly invariant.
Interestingly, the total number of proposals also does not change much, some dips and spikes with the loss and availability of instruments, but the total is near stationary and some measure of the statistical saturation of the ability of astronomers to put together coherent proposals in a finite time.

Anyway, here is this year's lot, culled from a small sample of fb posts:

Same-same...
