Picture
ISS, flying 400km above Earth surface at a speed of 27,500 km per hour is the largest man made flying machine of enormous 100 meter in size. But at that distance, it appears to our eye with an angular size of only 50 arc second. Even smaller than a small marble hold at an distance of around 50 meters. or the distance between Barpost and Mid Field of a football ground. One can well imagine how critical could it be to shoot this when infrequently ISS becomes visible from a specific small patch of Earth Surface as a solid black silhouette against the face of Sun, that too only for 1/2 second, on its way through its own precise orbit around Earth.
This was SWAN's fifth ISS Solar Transit attempt and the fourth successful one. Thanks to all including the local villagers there at the location.
