Folks, before I post pictures of the Sonmiani Rutjuga, let me put up details of a visible pass of the International Space Station (ISS) tomorrow (27/04/10). It is expected to be clear here in Karachi Insha Allah. The ISS will rise from the south-east and pass almost directly overhead (see details below). To get pass details for your location, you can either manually enter your co-ordinates or log-in (free) at heavens-above.com. For a given location, the ISS makes visible passes many times each month. And you do not need a telescope or binocular to see it.

Obviously you cannot see the huge satellite's shape with the unaided eye. The view through a telescope, however, is a different case. Here the ISS is seen transiting the Moon (composite image courtesy of Ed Morana):
