Determining the Lifetime of a Solar Granule

Granules on the Sun's surface (Neil Hurlbert)

1.

Your task is to determine the approximate lifetime of a solar granule on the visible surface of the Sun. Select an area then slowly and rhythmically repeat, "start, stop, start, stop" until you can consistently predict the appearance and disappearance of the cells, called granules. While keeping your rhythm, move to a different area of the video and continue monitoring the appearance and disappearance of granules A convective cell in the solar photosphere.

When you are confident you have the timing right, move your eyes (or use a partner) to the clock and determine the length of time between the appearance and disappearance of the granules and record your answer in the space below.
