Aurora hunters in Alaska got a double skywatching treat earlier this month.
Tour guide Ronn Murray, who lives in the interior of Alaska, has been wanting Starlight broadband service for a long time. He is still waiting, but at least he saw the satellites in the sky, he told SpaceWeather.com.
"We saw this while taking some guests out on our aurora tour," Murray said, adding, "It was really beautiful." The Starlinks were visible on Sept. 1 at 11 p.m. local time and again Sept. 2 at 1 a.m. Murray and his wife and business partner, Marketa Murray, witnessed both flybys and captured video the second time.
Starlink has come under scrutiny from the astronomy community in recent years due to the apparent brightness of the satellites. SpaceX has repeatedly said it is taking measures to dim individual satellites, but the community remains concerned, especially given the pace of SpaceX's Starlink launches.
SpaceX has launched more than 3,200 Starlinks into space and has approval to send up to 12,000, at least so far; it has also applied to an international regulator to launch 30,000 more.
The batch seen in Alaska launched Aug. 31 from Vandenberg Space Force Base in California, and SpaceX has already launched Starlinks three more times since then. The next launch is scheduled for later today (Sept. 14) from Cape Canaveral Space Force Station in Florida.
The satellites viewed in the video were not yet in their operational orbit, however. The satellites were at an estimated altitude of just 198 miles (320 kilometers), which is a little bit lower than the International Space Station flies.
Starlink satellites so close to Earth can "easily outshine a first-magnitude star," SpaceWeather.com wrote. (An example of a star that bright would be Deneb, in the constellation Cygnus.)
The operational altitude of Starlink is about 372 miles (600 km) high, where this batch was expected to go in the days after the launch.
As the satellites gain altitude, they fade from view from the naked eye. But they're still visible in wide-field telescopes as streaks that may interfere with asteroid observations and other forms of astronomy, critics have charged.
Starlink provides affordable service to remote areas that otherwise struggle to gain access to high-speed internet, SpaceX has said.
