Great tip thanksATCAA. If you select the "Air Traffic Control Assigned Airspaces" box on the SUA website in the "Map Layers" tab (to the right) it will show up. It's not a default so you have to check it manually.
FAA SUA Website
The BURNER ATCAA shows active today from 1600 EST to 1745 EST and again from 1830 EST to 2030 EST.
Under the Map Layers tab if you select "ALL SAA" and "ALL MTR/AR" and altitude boxes "FL290-<FL350" and "FL350-FL999" you won't miss anything.
