This is a screen grab taken at Morehead State University during our second DSN pass with ISEE-3 on 27 June. Morehead was observing the session and recording data. If you look at the larger version of this image you can see the ranging tone bursts being sent to ISEE-3 by DSS-24 at Goldstone. DSS-24 was broadcasting at approximately 10 kW.
