Of the 600 to 650 reported sightings (world wide) annually, there is no way to measure accurately which ones are more significant than the others. Many times, only in hindsight, do some aspects take on signifcant meanings. Some sightings are seen by many, these usually over urban areas. Some are sighted several nights/days in a row, some only a single sighting is reported. Only through researching each case individually will any important factors be revealed.
