[OT] Looking at the sun - Safe distance?

I was reading in the bathroom when I ran across an item written by
"Greg D. Moore \(Strider\)" on Mon, 05 Jan 2004
04:41:22 GMT, which said:

So, build a shadow box. An old shoe-box works great. I keep mine around
for eclipses. Should scale it up so I can watch sunspots.

For a few bucks you can get a mylar-like sheet of Baader Solar Filter
material. I used some to make a filter for my telescope and looked at
the sun directly, rather than by projection. Had to give it up,
though, since the telescope was a reflector and I was getting
sunburned over only the left side of my face.
