The epoch (point in time) of 1950 was mostĬommonly used during the middle to late part of the 20th century. Because of this precession and other related but smaller effects, astronomers convert the observed positions at any one instant into one appropriate for a convenient point in time so that locations can be more easily compared. The starting point (0 degrees = 0 hours) is currently in the constellation of Pisces but is moving slowly although constantly (it takes about 26,000 years to make a complete circuit the major component of this motion is called the "precession of the equinoxes"). It is measured in either degrees (0 to 360) or in hours, minutes and seconds (00h00m00s up to but not including 24h00m00s). Right ascension is analogous to longitude on the earth's surface.
The Big Ear radio telescope can observe in the 100-degree range of declination from approximately -36 degrees to approximately 64 degrees. Its range of values goes from -90 degrees (at the south celestial pole) through zero (on the celestial equator) up to +90 degrees (at the north celestial pole). Declination is the angular distance above or below the projection of the earth's equator onto the celestial sky. The next two groups of numbers on the computer printout (just to the right of the center of the row) are the right ascension and declination converted to epoch 1950.

Thus, the "6EQUJ5" code in channel 2 means successive intensities as follows: 6 -> the range 6.0 - 6.999. They used a system of only one alphanumeric character to denote the signal strength. Each of the first 50 columns of the computer printout shows the successive values of intensity (or power) received from the Big Ear radio telescope in each channel (10 kHz wide) in successive 12-second intervals (10 seconds was used for actual sampling and another approximately 2 seconds was needed for computer program. It involved a short duration high energy pulse. Originally designed by Point & Click Software, Inc.On August 15, 1977., SETI received a 1 shot signal that many have described as a WOW signal.
