You know what impresses me aside from the video and the analysis being done? How white your teeth are in that profile. I am impressed.

Look at the top edge of the Moon after it passes.
Push/pull of atmospheric air currents is visible making the Moon appear to oscillate slightly.
Only something large and traveling at good clip could create these "ripples."
The concept was formulated by Leik Myrabo, an associate professor of mechanical engineering at Rensselaer and Yuri Raizer of the Moscow-based Russian Academy of Science's Institute for Problems in Mechanics. It was apparently demonstrated late last month in tests at Rensselaer's Mach 25 shock tunnel.
According to Myrabo, the concept would offer designers the capability to actively control the external aerodynamics and thermodynamics of an advanced transatmospheric vehicle by substituting directed energy for mass-typically in the form of a sharp nosed structure. With this capability, traditional hypersonic design rules would change, and ultralight, blunt-bodied, lens-shaped or saucer-shaped single-stage-to-orbit vehicles could emerge.
Traditional sharp-nosed hypersonic vehicles generate a conical bow shock wave that causes massive heating at the tip of the craft's nose. The air spike concept uses concentrated energy projected forward off a moving vehicle to drive air radially from the path of the craft and to transform the traditional conical bow shock into a weaker, parabolic-shaped oblique shock-one tilted strongly aft with respect to a hypersonic vehicle.
SUPERSONIC AIRCRAFT SHOCK WAVE ENERGY RECOVERY SYSTEM
This invention outlines excitation means to transform the linear momentum of an underwing energized jet into rotational form in a selective manner to provide an asymmetric shear layer to increase compression wave reflection from the forward undersurface of a supersonic wing (39). The wing compression energy is thereby recovered into useful work as an increase in pressure on the upward reflexed wing backside. The upper surface of the shear layer is comprised of an array of vortices (37u) whose rotation is opposite to the wing circulation, providing the required angular momentum reaction. The upper wing surface is flat to avoid generation of waves and an adverse angular momentum reaction above the wing. The vortices (37u) below the wing are compressed by the underwing pressure, comprising a pressure shield to enhance the reflection. The shear layer/vortex array (37u) grows in the stream direction due to augmented mixing with the underwing gap flow (42), which is turned and deflected upwards to provide a further increase in pressure on the upwards reflexed wing backside. Fuselage bow shock energy is also recovered into useful work by a forward ring (180) reflecting the conical shock inwards onto a suitably inclined shoulder. An extendable nose spike (192) allows the ring to intercept the conical bow shock at off-design Mach numbers. The system in principle obviates wave drag to provide shock-free supersonic flight with improved efficiency and no sonic boom.

This image is the position the scope and Moon were at (only different day and time). The scope was outside the garage in the driveway. The Moon was close to the images location. The scope is pointing WSW for that time of year (spring).

i think you may have captured something really really interesting. maybe it was a hypersonic vehicle test ?
