2nd "restrict your remarks to the weather"

"Crepuscular rays, are rays of sunlight that appear to radiate from a single point in the sky. These rays, which stream through gaps in clouds or between other objects, are columns of sunlit air separated by darker cloud-shadowed regions. The name comes from their frequent occurrences during crepuscular hours when the contrasts between light and dark are most obvious." (Wikipedia)

If you read that and were thinking "what on earth does crepuscular mean?" I didn't know either, so I looked it up. If you are really smart and somehow knew it already--that's grand, great for you. You could have told the rest of us that "crepuscular" refers to the time near dawn and dusk. The root is from the Latin crepusculum, meaning "twilight."
Isn't that nice? Hmm. Well. Here's what I else didn't know:

"Crepuscular rays" can be found not only in SUNSETS,

Taken from Black Mountain Tower, Canberra

But are also called the same when REFLECTED

This building is somewhere in San Fransisco


C-rays can also be INDOORS,

St. Peter's Basilica (as in, Rachel really wants to see)

and aren't merely solar, but LUNAR.
