10 seconds were used to obtain the average intensity for each of 50 channels and approximately 2 seconds were used by the computer to process the data and analyze it for possible interesting phenomena.

During each 10-second period of data acquisition, one intensity was obtained each second for each channel and then the 10 values obtained over the 10 seconds were averaged for each channel.

The left hand half of each row shows the intensity for each of the 50 channels with channel 1 leftmost and channel 50 rightmost.

" in the left margin of the computer printout opposite them.

After I completed the review of the rest of the printout, I contacted Bob Dixon and Dr. Kraus, the Director of the Big Ear Radio Observatory. Then we began an analysis of what has been called for 20 years the "Wow! Analyses have continued even through recent years as ideas needed to be tested.

The Big Ear radio telescope can observe in the 100-degree range of declination from approximately -36 degrees to approximately 64 degrees.

Right ascension is analogous to longitude on the earth's surface.

Let me describe the main features and some of the details about the computer printout.

This section will deal with the meaning of the numbers and characters in the printout itself.

Bob wrote most of the initial software to handle the data acquisition and some basic analysis.

I handled the rest of the software, especially that involving some of the more involved analysis of the data (including search strategies).

This is helpful if you are not able to read the entire document in one sitting. source radio emission entered the receiver of the Big Ear radio telescope at about p.m. Thus, at the time this article is being written it is just past the 20th anniversary of the detection of that now famous radio source.

What have we learned about that signal over the past 20 years?

Both of us had other jobs so this was done in our spare time.
