Thanks for helping us analyze Breakthrough Listen data from the Green Bank Telescope! Berkeley SETI engineer Dave MacMahon takes us behind the scenes into the server room at Green Bank where the Listen instrument lives, and we also interview Green Bank director Karen O'Neil about keeping computers cool in our latest video: https://youtu.be/-gQocykdo1Y

Looks good...lets hope it is sustained and we hit that elusive signal...
Good job and thanks!

Excellent. Also many thanks to the residents of the United States National Radio Quiet Zone for not getting us excited by an E.T. signal which is actually a microwave meal :D

Very interesting. It must be quite a task to prevent water leakage from the green cooling pipes! Thanks for keeping us informed.

Just wondering, will we be taking any data from the Square Kilometer Array? http://skatelescope.org/

I ask because I'm anxious to look around the Sth. Celestial Pole

We're going to need to wait till 2025 before the Square Kilometre Array begins operating.

I believe that the Radio Telescope at Parkes (Australia) will be contributing via the Breakthrough Listen Initiative.
I think that is likely the second half of 2017.

But Seti still piggybacks onto the data wherever it is from. As we don't have our own dish, we can't control where the dishes we do use are pointing. People say as you haven't found anything in 18 years perhaps you are looking in the wrong place. That is a major drawback in the whole seti project.

What we needed was Nitpicker up and running to do a second sift and make a list of likely candidates for re-observation. Then we could have approached the dish operators and asked for some time at those locations. But it never happened.

You must keep up to date Chris, Nitpicker is dead and buried, Nebula took its place. ;-)

I really like the idea of using water cooling tubes to keep all those racked drives from roasting themselves. If ever ultraviolet lights get installed giving it that TRON effect (https://i.ytimg.com/vi/JbiEeEA1b9Y/maxresdefault.jpg) certainly turn down all those flourscent lights and provide us with a photo. Just lets keep fingers cross they never leak. :P

I've been trying to run my own little laptop as much as possible throughout this weekend, and in a few minutes its turning off with it going back on later today. The search goes on.

Awesome video! Watercooling for life- it's the only way to go! I set up an EK cooling solution about a year ago and I'll never go back to passive cooling with fans & sinks. It's almost zero maintenance and whisper quiet. Keep that SETI data flowing, you all are doing a great job up there!

That does not change the fact that ANY data that Seti obtains, back then or even now, is piggybacked from wherever the dish we use is pointing, and NOT in our control.

Only for the Arecibo data. All of the BLC work units from Green Bank are targeted and the instrument directed by the BL project at the time.
