Big Bear Solar Observatory (BBSO) is one of four solar
observatories capable of making high resolution observations
of the Sun, which are critical to understanding the dynamics
of our magnetically active star.  The drive to understand our
star arises from both scientific and practical reasons.

Data from BBSO have provided a seismic sounding of the
solar interior, which have advanced our knowledge of how
our star lives its life.

Recently, we have been observing the dark side of moon, or
earthshine, to quantify global warming.
