The LASCO C2 and C3 coronagraphs on SOHO have been recording a regular series of images of the corona since May 1996. This sequence of data covers the period of solar minimum, the increase to solar maximum, and the beginning of the decline toward the next solar minimum. The images have been analyzed to determine the brightness of the K-corona (solar photons Thomson scattered from free electrons). The total brightness of the K-corona is approximately constant from May 1996 through May 1997. The brightness is then seen to increase steadily until early in the year 2000. The structure of the K-corona changes dramatically with solar cycle. The shape as seen in C2 becomes almost circular at solar maximum while the C3 images continue to show equatorial streamers. The magnitude of the solar cycle variation decreases as the height increases. We present data animations (movies) to show the large-scale structure. We have inverted 28-day averages of the white light images to determine radial profiles of electron density. We present these electron profiles, show how they vary as a function of both latitude and time, and compare our observed profiles with other models and observations.
