Venus 'moves' fast enough that after a week or two of cloudy weather or just not being out and about at twilight, it's a 'new' object and can
startle people. There was a Russian airport about a dozen years ago that was shut down for an hour when a flight crew taxiing for takeoff reported a
UFO hovering at the end of the runway. Jimmy Carter got spooked by Venus. And yes it does seem to dance around sometimes, and scintillate colors.
My most extraordinary experience observing Venus was watching it rise from behind a rocky massif east of my hotel, and realizing that it took a finite
time -- at the range to the cliff edge, about ten seconds -- to transition from invisible to full bright. By stepping left and right, I found I could
dim and extinguish it, then 'rise' it again, a matter of about 20 cm in position shift. Stars, of course, blink on or off when occulted, instantly
-- no ramping of brightness. I was detecting the non-zero angular size of the planet. It was awesome to realize that even without a telescope, but a
good guess at the scale of the solar system, I could 'guess' the planet's diameter to within an order of magnitude.
Try this at home.
