You didn't ask for this, but since you are reading all the drops (VERY GOOD IDEA FOR EVERYONE !), here are my notes on Corona based on q drops. Corona = see also keyhole. CIA Satellites that map earth, resolution of 6 ft, built by Lockheed Martin for CIA and Air Force. Now Boeing has the contract.
Corona 1, 4, 8, 16 all taken down as of 8/30/2018. Blind eyes in the sky.
Keyhole (KH) - keyhole reconnaissance satellite, orbiting Earth > 30 yr, take overhead photos for military missions, looks like Hubble, but facing our planet. Altitude abt 200 mi. Cannot hover, not real time. Black/ white images. Can see things 5 inches or larger on ground. Probably can't read house #, but can tell if there is a bike in yard. Keyhole became: Google Earth Enterprise.
