(or about 20 magnitudes from the sun itself). I'd think the full moon shines at mag -12.4, a bright flare about -8.4, or only 40 times fainter. Full moonshine is quite bright and casts shadows, but it still makes forty times fainter really difficult ? --------------------------------------------------------------- -- bjorn@tt-tech.se (office) b_gimle@algonet.se (home) -- -- 59.2237N, 18.2286E, 44 m http://www.algonet.se/~b_gimle -- -- SeeSat-L / Visual Satellite Observer Home Page found at -- -- http://www.satellite.eu.org/satintro.html -- ---------------------------------------------------------------
