The image above is the result from my first attempt to shoot the
International Space Station (ISS) transiting the Sun. This
transit took place on July 26, 2022, at 17:41:07 local time
(15:41:07 UTC) in Cabras, Sardinia, Italy. At the time of transit, the
ISS was approximately 700 km (435 miles) above my home and its apparent
size was 38 arc seconds.

The space station is about as big as a football field, and its orbital
speed is almost 28,000 km/hr (17,400/mph. Note that the first module of
the station, called Zarya, was launched in 1998 from the
Baikonur Cosmodrome, in Kazakhstan. The operational life of the ISS
has been extended until 2030. In addition to the silhouette of the ISS,
a few sunspots are also visible in the active regions AR3062 and
AR3066.
