The WOW! signal's measurement took the average signal strength over 12-second intervals. The average intensity's peak was just over 30-1 signal to noise, meaning that the 12 second interval had an average strength of 30-1. But evidence suggests the signal came from a point source. Has anyone ever done the math to estimate the point source strength? Is this even possible?
The plot is pretty straight forward. 6EQUJ5 puts the peak signal between Q and U, closer to U. The letters represent two digit numbers, 1-9, then A-Z. A being 10, Z being 35. U was the highest signal strength received equivalent to a 30.
Wikipedia has a nice summary of the event. The location is discussed here with some margin for error due to there being two listening devices and the design being, as I understand it, somewhat less than ideal.
While the signal remains unexplained, it was some 30 times stronger than baseline, but 3s and 4s were fairly common. It was only 7-10 times stronger than signal strengths they received regularly. I lean towards it being a natural but unexpected event, but there's not sufficient data to close the case, so to speak.
