My name is Thomas and I am a watch face designer. Astronomy is not my strong suit but I'm trying to incorporate some cool things into my designs. I have joined this forum for helpful information. I posted my 1st question about SR and SS.
Good day!

Hello and !

Have fun, stay curious, and avoid bold letters!

Lol didn't realize my font was on bold.

I fixed it up for you.

BTW, I also fixed up your thread title on your thread start. "SR" commonly is used for Special Relativity in the technical forums, and one seldom see Stainless Steel and Special Relativity discussed in the same thread. Perhaps they are common shorthand for the "Sunrise" and "Sunset" as you intended, but I hadn't seen that before.

Yes it was short for Sunrise and Sunset, thanks.
