Zoomed-In View of Mercury Transit from IRIS

On May 9, 2016, a NASA solar telescope called the Interface Region Imaging Spectrograph, or IRIS, observed Mercury crossing in front of the sun – an astronomical phenomenon known as a Mercury transit. The movie shows a composite of the IRIS imagery, in the inset, and imagery from NASA's Solar Dynamics Observatory, or SDO, as the golden background.

Wow thank you! I couldn't even spot it on the zoomed out version.

Why is there a sine curve in the zoomed in footage?

[TheWebstaff]

Why does it zig zag in the zoomed in video? does the telescope have a small oscillation going on?

How much of the Mercury circumference crawliness is due to 1. interpixel nonlinearity averaging, 2. Earth atmospheric scintillation, 3. solar spicular refraction...

If we introduced heat to Mars. It will rain

The ISS is moving up and down at a noticeable rate - knowing the transit time, the orbit periods, and the sinusoidal movement, you could calculate the period of the ISS.
