Full details about upcoming CLEs can be found below, along with the results of the latest one in .pdf format.

The links above will take you to the various sections of the database, and you can also find a very useful list of beacons operating in this month's CLE frequency range by clicking on the 'CLE SEEKLIST' button at the Rxx site:
