Light flash every 42-43 seconds, remains stationary in sky almost due south.Observed a bright flash of white light in the sky in the Virgo Constellation each night from June 12th thru June 15th. The light was kind of like a strobe and flashed briefly about every 42-43 seconds.We observed it each night starting around 9:30 pm Central Standard Time and would watch for several hours and determined that the light stayed in the same location in the sky and the Planet Saturn and Spica which were in the area at the start would move off to the west and the light would remain in the sky at almost due south.We were observing in an area which has very little light interference and is located at the following location: 36* 58’ 13” N 90* 21’ 34.88” W at an elevation of 390ft.There were seven in our group ranging from 35 to 65 years of age and we all saw this flash for hours each night. We also were at the same location around this time last year star gazing and do not remember ever seeing this flashing light before
