    Sets Sun Video
AI Thread Summary
The Wunderground video on a Roku device shows a time-lapse of a sunset that appears to drift north instead of south, which is unexpected for locations in the Northern Hemisphere. The user questions whether this could be a reverse image or an error, as they recall the sun typically setting to the south at their latitude of 39°N. They note the sun's usual path: rising in the east, reaching its peak in the south, and setting in the west. The discussion raises curiosity about the accuracy of the video and whether others have observed similar phenomena. Overall, the video prompts questions about the representation of solar movement in time-lapse formats.

My roku device has a channel for wunderground.com, which shows the weather. But it also shows a time-lapse video of the past 24 hours in a local neighborhood. The caption says "Facing West," and you can indeed see the sun setting in the evening as you would expect.

But in the video the sun drifts to the right, North, as it sets. I haven't been able to wait around for sunset recently to check, but I only recall the sun appearing to drift South as it sets here in the Northern Hemisphere at about 39°N.

The only conclusion I can draw is that it's a reverse image. But I wonder how you can do that by accident. And if not by accident, I wonder why. Has anyone else seen this?

The sun rises in the east, travels south as it gets higher, then wraps around and travels north as it descends and sets. In fact, you can tell time by the direction of the sun: 6 AM = East, 12 PM = South, 6 PM = West.
 
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
