 +The observation was April 1, 2017, Here is an email sent to Toby from one of their operators, Mark:
 +
 +  Toby, 
 +  
 +  FYI we concluded with SETI / ATA at about 6:56 today after a long transmission of about 20 minutes in length. The 
 +  amplifier stayed cool with only a 2 F degree increase in cooling water temperature with the continuous transmission. 
 +  
 +  We will continue with SETI by email and will ‎send some photos of the station. Gerry has sent a concluding note 
 +  (below), and thank you for opportunity to participate Gerry. 
 +  
 +  This initial effort has worked well and we will make the station available anytime should SETI seek additional 
 +  reception data for their work from the moon or other objects such as satellites.

 +  Subject: the moon did bounce
 +  
 +  Hi Everyone
 +  
 +  Success!
 +  
 +  Well thanks very much to Toby and Mark in Vancouver, we got some good 
 +  data with the ATA measuring their transmission bounced from the moon. 
 +  We're using these observations to test some ideas about a large-scale 
 +  double slit experiment. With two synthetic beams at the ATA, pointed 
 +  toward different small parts of the moon, we want to make a quantitative 
 +  measurement of the interference between the two beams.
 +  
 +  As you might imagine, the moon's surface is very rough on the scale of 
 +  the radio wavelength (~23 centimeters). So the moon acts like a diffuse 
 +  reflector. [We're avoiding the specular reflection.] The question we 
 +  ask is, can you still see interference between the signals on the two 
 +  slits even though the reflector is very diffuse. My prediction is that 
 +  we will see interference, but Stu has suggested that maybe we won't. The 
 +  point is, we're not certain what the results will be and this is why we 
 +  tried the experiment.
 +  
 +  We could clearly see the reflected signal in our instruments, so we know 
 +  we have enough signal to noise to answer the question. We won't have a 
 +  quantitative answer for at least a couple of weeks because we're 
 +  distracted with some other high priority work at the Institute. This 
 +  experiment is just a side project.
 +  
 +  Anyway, thanks to everyone who participated!
