Un articol interesant de pe CN mi-a atras atentia.

Este scris de un meteorolog cu pasiuni astronomice.

Din continut:
"ow, imagine this: You setup and align your observatory scope or your “go-to” telescope during the day when skies are clear, or even on a previous night. Then, armed with the latest visible satellite images late in the afternoon you bring someone over to observe who thinks you are nuts for even trying on a “Cloudy Night”. Ah, but YOU know, those are high thin cirrus clouds, and in fact, at times, you may even be able to pick out your planet without optical aid. If you really luck out though, it will be “just cloudy enough” to be absolutely invisible without the scope, and yet totally visible with the scope peering through the high clouds, now that will impress friends and family!"
Din aceeasi serie, imi amintesc o pagina web cu observatii in timpul zilei (cu GOTO bineinteles ) )

eh.. observatu pe nori mi se pare fara nici un haz.
in schimb observatiile diurne sunt chiar misto si nu-i nevoie de nici un go to. de exemplu, pe mercur l-am vazut de mai multe ori in timpul zilei, decat in crepuscul. am vazut chiar si o ocultatie a lui venus de catre luna in mijlocul zilei... prin 2004.
