A magnitude -7.0 flare from the left antenna of Iridium 25 satellite on 23rd February 2016.
Visually this was an eye-catching bright flare, about one hundred times brighter than Sirius, the bright star top left (magnitude -1.5) – the brightest star in the entire night sky.
This image consists of three stacked exposures, each of eight seconds duration and a delay of around one second between each.
This flare was accurately predicted for my location by Calsky.com. The satellite was 791 km above Earth and 904 km from the camera.
