Space Station Flare Captured On Film

I’ve been watching this short video clip over and over. It may only be two seconds long, but it is such a unique view of the space station that I find it mesmerizing. Each time the animated GIF loops, another detail seems to reveal itself.

It’s also kinda hypnotizing in a rhythmic way; the space station appears to turn and boost away into the black of space, but just before its massive solar arrays capture the sunlight, dazzling the observer with a flash.

Is it me, or are those solar panels reminiscent of the sails hoisted up the masts of canon-touting battleships before the age of iron-hulled vessels and steam-powered engines? These slightly fuzzy images could even be from the turn of the 20th Century, when one of the first movie cameras filmed a ship steering out of port.

Of course, this isn’t a wooden ocean-going ship, it’s the space station, in orbit. And the video was taken with a modern digital camera through a 16-inch Dobsonian telescope by a highly skilled amateur astronomer called Nicolas Biver from Versailles, France. The reason why the station appears to “turn” is because the perspective of the observer changes as the station flies overhead, he did a great job of tracking it.

On April 28th, Biver tracked the space station through his ‘scope. Whether it was intentional or not, he was fortunate to capture an intense flare as the space station’s solar panels reflected sunlight at his location. The resulting flare was much brighter than Venus (after the Moon, the station is the second brightest object in the night sky). Usually when I hear about observations of flares made by stuff in orbit, I usually think of Iridium flares that occur at predictable times and locations, providing a target for observers on the ground to capture a meteor-like streak across the sky. The Iridium satellite network provides a great chance for astronomers to see the reflected light when the angle between them, the satellite’s solar panels and Sun is just right.

My astronomer friend Tavi Greiner (who has just joined the Astrocast.TV team as host of Our Night Sky, be sure to check it out!) is very skilled at observing the Iridium flare-ups, and as can be seen in this image, those things are bright.

However, on the 28th, it was the space station’s turn to reflect some light for Nicolas Biver.

In March, Space Shuttle Discovery completed the construction of the ISS solar arrays during the STS-119 mission. Over a series of space walks, the solar array had its area boosted to 16,000 square feet. With this extra surface area, comes the potential for very bright flaring events.

  1. I’ve been staring at that ISS video over the past couple of days, too. It truly is mesmerizing, especially when one remembers the people living within, going about their daily lives just as we do, down here on Earth.

    Thanks for the iridium flare mention. I encourage everyone to make a point to see a flare at least once in their lives. They are an unforgettable sight.

  2. Nice! I love observing flares, it’s nice to finally see one up close. Flares are also an excellent way to impress people… you look like some kind of astronomy wizard when you point to an area of sky just before one of these things brightens. I have found that many people who aren’t interested in space or astronomy at all still find these fascinating; it’s a great way to start a conversation.

  5. Lovely images… but I still don’t understand your explanation of the apparent rotation of the station. I can’t see why the viewing perspective would change over such a short viewing interval.
