    Debunked: "Deadly Ultraviolet UV-C and UV-B Penetration to Earth’s Surface:" [Stray Light]

    It is striking the group that made the findings, does not FIRST question their data, but directly concludes that it must be the light/atmosphere and not a faulty spectrometer and/or wrong measurement method. When there is huge "database" of measured spectral solar data, originating from many...

    Debunked: "Deadly Ultraviolet UV-C and UV-B Penetration to Earth’s Surface:" [Stray Light]

    All has been said so far, but how could the paper have been accepted for publication? I cannot imagine the whole board reviewing the paper all agreed just like that? Found the peer-review history: http://www.sciencedomain.org/review-history/23870

    Debunked: "Deadly Ultraviolet UV-C and UV-B Penetration to Earth’s Surface:" [Stray Light]

    The paper explains a lot, but just not enough information is given about how the system works and if they (the operators) took care enough to prevent wrong data. The type of instrument they used is used everywhere, in labs and in the field. As I have used these type of spectrometers extensively...

    Debunked: "Deadly Ultraviolet UV-C and UV-B Penetration to Earth’s Surface:" [Stray Light]

    Ah, handheld spectrometers are great! But not at 350nm and lower.. It is well known fact, if they would have the experience using them or any photometric device.. The authors should have asked a photonics engineer first, smh..

    Perhaps: 3) compression video stream algorithm or even 4) applied image processing filter from the broadcaster to "enhance" or for whatever reason?

    Geoengineering Watch and the Wagon Wheel Effect

    Interesting you mention that. At work I use a 500Hz image acquisition system and in combination with a LED torch, you can (not naked eye) see the effect of the frequency of the LED in the frames as black, horizontal rectangles moving top down. Bit annoying, as I always need to use incandescent...

    NYT: GIMBAL Video of U.S. Navy Jet Encounter with Unknown Object

    Just to add a bit more to the case. What happens optically can be compared to the so called "nasmyth focus" in astronomical telescopes. For any scientific instrument mounted on this position, a "de-rotator" needs to be used to rectify the (rotating) stellar field. It it a fully optical unit...

    NYT: GIMBAL Video of U.S. Navy Jet Encounter with Unknown Object

    It would have been helpful if in the video another high brightness item was visible, as then we could have observed if that item also has the same flare effect, and more importantly, IF its (flare) direction is identical to the ufo, and also rotates. Too bad!

    NYT: GIMBAL Video of U.S. Navy Jet Encounter with Unknown Object

    I think the theory of the glare of the front window is pretty sound. The optical mechanical mechanism is indeed a gimbal based design, making the image rotate while using the gimbal mechanism. This is usually rectified by using an compensating optical element, or just by rotating the image...

    Welcome Thread - New Members Post Here

    Hello everyone, I am new to this forum but after some reading here and there I think this is the right place for me. Skeptical as I am, I like to find out the truth behind certain stories and pictures/video's. I was lurking on ATS for a while but there the majority of the folks are not very...
