The lists are in order as reported from January 1947 through December 2004. The timeframe reported represents 58 years (696 months). This list was retrieved from the above website on January 21, 2005. The total sightings reported during the 696 months were 29,580.

What I discovered upon placing these figures on a spreadsheet and consequently multitudes of charts and graphs was that there was a definite pattern showing that UFO sightings increase in numbers in consecutive months. After those consecutive months, the reported sightings decrease and then a few months later increase once again in larger numbers. This I found to be a possibility that UFO’s come and go in waves.

In order to discover the waves, I totaled each year and simply divided it by 12 to give me an average of reported sightings for each month. I then set aside each month that met that average. In doing so, I discovered that these months that met an average were all consecutive.

Within the 696 months, I discovered a total of only 35 variables that were questionable. 23 of the 35 variables represent a month found within the consecutive months in the column on the right, but are not of the average for that month. They are however, extremely close. The average total of the 23 variables was only 0.033045977. In other words, the total average of the variables only put them at 3 sightings off their mark for the average of that given month.

These are the following variables and their average. They represent the numbers of sightings within the consecutive months that are off their mark. 0.25, 0.75, 1.0, 1.33, 1.5, 1.5, 1.5, 1.5, 1.67, 1.83, 2.33, 2.75, 3, 3.42, 3.67, 4.0, 4.08, 4.17, 4.38, 4.92, 5.25, 7.25, 9.67. As you can see, not really any of them are off by much at all.

The remaining 12 variables represent numbers on either side of those posted in the column on the right' within a given year that are outside the grouping and of the necessary average or larger. There were only 12 out of 696 entries possible. This amount could be considered insignificant when you consider that 12 is only 0.017% of 696.

I found only one single exception to the rule, which I ruled out completely and was found in the month of September 1997. This single entry for September was off by 45.83. This is a considerable difference considering that no other variable was larger than 9.67. Because of the tremendous difference on that month while comparing it to the 696 months, I did not apply it to a variable whatsoever and instead assumed it could have been an occasion where UFO's could have all pulled back suddenly for some unapparent reason to us. No where else in the 696 months did this occur. I consider it fluke and probably only explainable by them. For that matter, the reporting website National UFO Reporting Center (NUFORC at ufocenter.com) may have an explanation as to the lack of sightings reported in September 1997.
