Notice: If you enable this, your location will be uploaded to SondeHub; making it publicly visible on the map for up to 12 hours.
You can report a recovery here. Enter the serial number (no type code, e.g. 'S1234567'), tick recovered/not recovered, and add some notes. If the sonde is not on the map, type its callsign into the top-left search box and press enter to retrieve historical data. You can then mark it as recovered. Optionally, you can use your location instead of the sonde's last location.
