 for an observation it has already requested. The first time an observation
-is requested, it is downloaded from the SatNOGS network to the `download`

 ## SatNOGS Observation Data Mirror
 The downloaded waterfalls are available below via `http` and `rsync`.
 Use this instead of downloading from SatNOGS to save their bandwidth.
