(Correct) the size of a city, 20-30 kilometers across. Some eruptive prominences have reached heights of more than 1 million kilometers above the photosphere; Earth would be completely lost inside one of those awesome displays (Figure 2). The latter statement may well be true, but most of the energy put out by the Sun is escaping precisely where the photosphere is brightest - in the granules . When observed at the centre of the solar disk, spatially averaged lines formed at the base of the photosphere (around an optical depth of 0.1) have a Doppler blue shift of typically 0.3km/s; for lines whose core is formed at the top of the photosphere (optical depth around 0.00002) the observed Doppler blue shift is typically 0.05km/s. Each granule will last for about 8 minutes. A typical computation gave values of 895 and 727 G at 0 and 100 kin, respectively, with diameters of 1.9" and 2.2". .
