Strobing skies

Took the low serial # EX1 (firmware v.1.03.5-something) outside to shoot the Spring tree color. Beautiful blue skies, puffy white clouds that turned to a hail and thunderstorm a couple hours later. Cam was locked down on a Sachtler head, close focused on tree blossoms (no macro), facing ENE. 1080/30P, Doug Jensen's outdoor pic profile, shutter off (I'm pretty sure - I never change it), WB was about 5800 or so. Got pretty breezy and the blossoms were swaying pretty hard.

When I looked at the files, in a few clips the blue sky was strobing like crazy. Visibly pulsing brighter fairly rapidly. Checked on both my MacBook Pro/Dell LCD (an older good one, not a TN) setup, and on my Mac Pro/EIZO LCD monitor -- same thing.

What the heck am I doing wrong? Is this a combination of CMOS chips and the rapid branch movement? It strobed even when they weren't moving fast, and not in all shots. Was not shooting S&Q. Is this a progressive thing? Aliens invading? I was pointing the general direction of the Army's largest ammunition factory a few miles away, but they don't make pulsed laser satellite death rays, just bullets. Anybody else see this happen?
 
Uhh, because I don't know what I'm doing some of the time? Okay, MOST of the time.

It wasn't -- I was thinking maybe I bumped the switch. It was on, set to SPEED/60.

Flicker was on. I searched for "strobing," didn't think to search for "flicker." Thanks for the assist!
