Description |
A normal day on the sun... the
solar maximum has passed and only a few sunspots are seen in visual
wavelengths. Granulation is obvious. A more promising sunspot
group is rotating into view on the left. Featuring an apparent
visible disk diameter of over 32 arcminutes, the sun was just a little too
large to fit on the 10mm width of the CCD chip in this prime focus image. |
