Sighting Reports 2010
Anomalous Object Shows Up in Photo of Temple of Kukulcan
Zoom in of Object In Photo of Kukulcan Temple.
Photo of Kukulcan Temple and Object at Full Resolution.
Yucatan is in the Yucatan Peninsula in Mexico.
Date of Sighting: September 1, 2010
Time of Sighting: 10:45 or 11 PM Local Time
Location of Sighting: Yucatan, Mexico (See Map)
Description: The was taking photos of the Mayan Temple of Kukulcan and noticed a bright object in the sky near the temple. He took several photos, but did not see the object in the other photos.
Note: Is the anomalous object real or a lens flare or other anomaly? These photos have been edited by the photographer so a hoax cannot be ruled out. The photo was taken in Mayan Ruins. This area has been a "hot bed" for UFO sightings.
Comments Received on September 19, 2010: Hi Bill. This looks like a refraction pattern lens flare which includes the focal ratio aperture hexagon shaped reducer. All medium to high quality cameras have a lens fitted with focal ratio adjustments. Whenever a camera lens is used with any adjustment of the F-stop ratio the collapsing doors will change the outside shape of the light path from circular to the multisided shape of the doors The focal ratio, also known as F-stop scale, is adjusted either manually or automatically. A lens with an open aperture of F-2.8 may have a aperture reducer to increase the ratio to F-20. Increasing the focal ratio improves focus and attenuates light when a camera is set with higher ISO values. The aperture adjuster for F-ratio uses a collapsing multisided door that produces hexagon or octagon shapes. The F ratio adjuster can be observed with a manually adjusted camera lens by removing the lens and rotating the F-stop adjustment ring. Also within the hexagon pattern are diffraction fringe rings that are caused by the characteristics of the camera lens. These diffraction rings are actually used in grading a telescope's optics. The wave front accuracy of a telescope can be calculated by observing on out of focus star and comparing the observed diffraction rings to reference formulas and charts. I hope this helps.
UFOs Northwest Response to Above Comment: I know the commenter and regard him as an expert on cameras. He is also an amateur astronomer. The light clearly has a hexagonal (six sided) symmetrical shape. This shape was likely the result of the camera aperture.
