Metop-C Flare & Airplane

If you have followed my blog long enough, you might recall that I like to photograph Iridium flares. Link to examples. The constellation of 66 communications satellites provides a worldwide phone system. I get email notices when a flare, sunlight reflecting off an antenna, is visible at my location.

Recently, I have received notices about flares from three weather satellites of the European Union (EUMETSAT). They are known as Metop A, B, and C. Their polar orbits and altitude allow weather to be monitored continuously. Antennae sometimes reflect bright sunlight down to Earth causing a flare. I was notified of one at 9:54pm local time on 9 Jun 2019.

Using the NightCap app on my iPad, I set it on the sidewalk, angled it toward the correct part of the sky and let it capture a time exposure for a couple of minutes. A small plane flew over at low altitude just after I started the exposure. Right after that, the Metop-C satellite passed over leaving a faint flare trail. Both were going north, lower left. Notice the handle of the Big Dipper drawn in the top left. The two pointer stars of the dipper are not visible. I like when serendipity happens.
