Stargazers may be getting quite a show this week.

Comet Pan-STARRS is expected to be visible in the Western sky this week, mainly Tuesday and Wednesday evening.

The key word is "expected"; it's hard to predict just how spectacular a show we're bound to get.  Comets are often "fizzles," as was Halley on its last visit.

So, look to the skies this week; maybe we'll get lucky...
