SETI@home is getting data from Green Bank, Einstein@home is getting data from Parkes. This means that BOINC programs are treated as real science projects. I am crunching data from LHC as an alpha tester.

The GBT is in my state. I was wondering what they used it for. 450 seconds better than none.

Hello ! I'm in the State of West Virginia to. 450 seconds is better than no seconds at all. Man, I'm EXCITED ! Yep, even old timers ike me get wound up every now and then ! Just like you, I also have wondered what they used that telescope for. The first time I was there, I inquired about The SETI project, and the people down there had a good laugh. Second time I was there, they showed me the little telescope that SETI used, and they did brag a little. I wonder what they are thinking now ? The wife and I might take a little trip down there, just to ask about it.

Hello ! Thanks for the update, and let me be the first to say, "Welcome To West Virginia" !! Green Bank is only a few hours from my location. I wish you well with the work that you are going to do there. I've been there several times, and it was impressive. There is a MONSTER radio telescope there, plus many others. Any idea as to what radio telescope that you will be using ??
Once again, Welcome to WEST Virginia !


Well dont drive out there with a signal generator and a morse key sending Hello, Eric!

Yep. You are right about that. Green Bank is a noise free area. Cell Phones won't even work there. Lord... I LOVE that area ! Very quiet, and no cell phone. HEAVEN !! ;)

Grad student Andrew Siemion reports that new modifications to a data recorder at Green Bank that we need for our Kepler SETI observations are now complete, thanks to a huge amount of help from Paul Demorest, a former grad student and one of initial authors of AstroPulse. Our first hour of test time is scheduled for this Saturday, 17:30 EDT. We'll be observing with 450 seconds per target on 90 Kepler field stars with interesting planet candidates (~habitable zone, ~Earth size, ~Earth period, ~several planets), then do a raster scan of the entire Kepler field.


Will S@H be piggybacking on the telescope once the reobservations are done? Or is this a one-time deal?

In one hour of observation, assuming no time lost for repositioning the antenna and that each star is a unique observation 8 stars can be observed in each 1 hour slot. To observe the 90 suspects will take 11.25 hours of observation - call it twelve, so the "slack time" of 45 minutes will either be used to reposition the antenna or for the raster scan.
If my assumptions are wrong then the sums change, but its still going to be an interesting time when this data becomes available for processing.

The UC Berkeley SETI survey focuses on Kepler’s top Earth-like planets news release is very informative.

Interesting reading. I'm taking an educated guess when we start to process this data the tape(s) on the Server Status will read something like 08My11aa. (8th May was when data started been recorded) Will this data be made into Astropulse work too?

when , how do we get to help out with this ?
This is the most exciting news for ages..... I am even resurrecting a Q6600 for the job, to go with the 2 x i7-920s.

I have a feeling that a lot of people (myself included) will put everything they have into this work... CANNOT WAIT !!!!!

Please let us all know the details of when it starts , thanks.

I agree with Veebee. I'd LOVE to be able to dive into this work myself. Please let us all know what we can do, and when to be expecting to get the work units !

One little H.P. computer, working it's little heart out. ;)

I just hope that none of these planets were behind their star at the time the observations were made. I guess that was one of the factors taken into account during the candidate selection process.

Nice article, thanks! Sadly, it doesn't say if S&H will continue to piggyback on the telescope after the Kepler observations. Is this still undecided?

The link at the bottom of that news item http://seti.berkeley.edu/seti_at_the_gbt says that they will be using this equipment in future to piggy back on the Green Bank telescope

So it's just a q of waiting a few days or weeks 'til we start seeing the first units through I guess.

Hi! It did mention piggybacking but I did not see anything saying that recording would continue after the targeted search completes.

Eric, why 800 MHz? Is it a Green Bank feature or there is any other reason?
Tullio

The way I read the article, the search isn't at 800 MHz, it's a band 800 MHz wide. It could be from 100 to 900, or 500 to 1300, or something like that.
