Eclipses

There was an eclipse on the first day of Chinese New Year. A brief one! So brief that I didn't even see it at all. Some people say yes it did occur but didn't seem to, to me. Not in total darkness.

So my hunt for research on eclipse. How frequent it is? I seem to be having amnesia and it seems that eclipses seems to me that it is occuring more frequent then it used to. I used to understand the eclipse only turns up once in a blue moon. So what is the answer?

From http://www.space.com/scienceastronomy/top10_lunar_eclipse_facts.html quote:
Though you might not have logged many lunar eclipses in your life, they are common compared to solar eclipses, at least in one sense. Solar eclipses are fairly numerous, generally two to five per year, but the area on the ground covered by totality is only a few tens of miles (kilometers) wide, so it's rare to be in the path of a total solar eclipse. In any given location on Earth, a total solar eclipse happens only once every 360 years. Lunar eclipses are less frequent, but total lunar eclipses are visible everywhere that it is nighttime as the event takes place—essentially half the globe. Any given location can experience up to three lunar eclipses per year, as last happened in 1982. Some years there are none, as in both 2005 and 2006.

Still the history of occurences in eclipses
