The International Space Station (ISS) moves eight kilometers (five miles) per second and orbits the earth every 90 minutes. Within 24 hours, the crew of the International Space Station experienced 16 sunrises and sunsets. Despite how long the station passed directly between the earth and the sun, it was difficult to capture images of the International Space Station passing our nearest star.
June 24, 2020, NASA Photographer Joel Kowsky captured this situation from Fredericksburg, Virginia. The above image is a composite image composed of six frames, and the ISS is shown in outline when the ISS orbits 400 kilometers (250 miles) around the earth from right to left through the solar disk.
The image below shows the position of the International Space Station in its orbit. Kovsky took a picture of him at about 1:15 pm. Eastern Daylight Time in the United States. The transmission lasted about 0.54 seconds and was captured when his camera was shooting at 10 frames per second. Watch the bus video below.
Ten photos assembled in order, showing the International Space Station, with five crew members in silhouette at approximately five miles per second from Fredericksburg, Virginia at 5 miles per second from Frederick, Virginia Fly over Fort Worth, this is Expedition 63 NASA astronauts Chris Cassidy, Chris Cassidy, Douglas Hurley, Robert Behnken and Roscosmos The astronauts Anatoly Ivanishin and Ivan Vagner.

Kovsky said that many websites can help determine when the International Space Station crosses the sun, but weather and time are usually the main issues in taking clear pictures. Kovsky said: “Because the ground visibility path is very limited, having clear weather at a certain location is one of the biggest limiting factors for capturing buses,” Kovsky said, and his weather has disrupted recent attempts. When shooting the sun, proper safety equipment is also needed, because looking directly at the sun may damage your eyes.
NASA has previously released images of ISS crossing the sun, including during the total solar eclipse in August 2017. Recent transit images (such as the one below) also show insufficient sunspots because the sun enters a period of low solar activity as the lowest sun.
