Viewing a UFO over Luxembourg City

This document summarizes how I've examined a possibly-authentic video recording of a UFO over Luxembourg City, Luxembourg. I've used open-source software to:

1. Select interesting frames from the UFO video.
2. Extract (crop and interpolate) UFO closeups (enlargements) from the frames.
3. Create an online slideshow of UFO closeups.
4. Examine the UFO's features, including its components and activities.

Note: The UFOID website provides free UFO Detector software through which you can set up your computer and a webcam as a skycam system. If your computer records a UFO video clip (typically 10 seconds), you can submit it to the UFOID community for collective analysis. The UFOID website also includes video recordings posted by participants who use UFO Detector. For more information, please see Sharing UFO videos through UFOID.

UFO video
On 05/02/2016, a UFOID participant used a UFO Detector skycam system to record a UFO over Luxembourg City, Luxembourg. This participant's skycam system recorded the video through a 950nm infrared filter.

Note: To view this video frame-by-frame, you can download it from UFOID, and then use a VLC media player.

UFO closeups

Using procedures in Sharing UFO videos through UFOID, I've extracted interpolated closeups (enlargements) from various frames of the Luxembourg video.

Each uninterpolated UFO closeup has relatively few pixels, typically between 200 and 2500. Therefore, we cannot see details as clearly as we prefer because each pixel appears as a relatively-large square. However, graphics software uses interpolation to calculate many new pixels among the uninterpolated pixels, which smooths out the squares. While not perfect, an interpolated closeup helps us see general shapes more clearly than would the patchwork of pixels in an uninterpolated closeup.

UFO slideshow

I've created an online slideshow, Closeups of a UFO over Luxembourg, which lets you see clear, large, sequential images. As you scroll through the slideshow, you can see how the object changes over time. This slideshow consists of closeups extracted from 20 sequential frames. According to my measurements through a VLC media player, this skycam system recorded at approximately eight frames per second (0.125 seconds per frame). Therefore, this 19-interval slideshow, presents images recorded for a total of approximately 2.375 seconds (19 X 0.125 ≈ 2.375).

Note: My UFO slideshows are central to these analyses. I initiate each UFO-analysis project by creating a slideshow. Multiple, sequential images are more informative. No single image can show whether an object is making changes.

Here are a few images from my slideshow, Closeups of a UFO over Luxembourg:

Figure 1 - slide 09 - The dark spots around the bright object
add complexity. Are these spots part of the object? They
might be distortions caused by the 950nm infrared filter.

Figure 2 - slide 15 - Has the object split momentarily?
The top portion seems to have its own set of dark spots.

Figure 3 - slide 18 - Four small dark spots seem to form a square pattern.

UFO features

I've tried examining this UFO's features (components and activities), after extracting its interpolated closeups and creating its slideshow. In my opinion, if the Luxembourg video is authentic (not a hoax), this UFO is probably an object of unknown origin.

UFO components - This UFO seems to have a central white component. Various dark spots might be separate components.

UFO activities -  As I scroll through my slideshow, starting at slide 1, I think I see the object rotating anticlockwise.
