Li na página do SWPC: "During the spring and fall, GOES satellites experience eclipses in which the Earth or moon blocks the X-ray instrument view to the sun for a short period every day. Eclipse season lasts for about 45 to 60 days and ranges from minutes to just over an hour. At these times there is a gap in the XRS signal shown." Será que pode ser o caso, ou seja, um "eclipse" em que a Terra ou a Lua bloqueia a vista instrumento de raios X?
