Portuguese astrophotographer Miguel Claro captured an incredible image of the International Space Station (ISS) silhouetted against the Sun’s disc. On the day of the photograph, the ISS was 441.54 km away from Earth, traveling at an impressive speed of about 7.31 km/s.
Claro explained that the ISS, with a width of 108.5 meters, appeared with an angular diameter of 62.58β³ compared to the Sunβs 31.6β²βmaking the Sun appear 30.3 times larger than the ISS during the transit. The station completes an orbit around Earth every 90 minutes, but he had only 0.54 seconds of transit time to capture this fleeting moment.
To meet this challenge, Claro used the Apollo-M Max camera by Player One Astronomy, capable of recording 109 images per second in 16-bit. The final video, lasting about two seconds, includes 200 images, creating a stunning visual of this brief yet extraordinary event.
