Having waited a considerable time for an Iridium flare to show they now seem to be arriving in abundance. This one was Iridium 59 which achieved magnitude -3.2. Like my last Iridium post it just managed to hit its bright spot just as it departed the frame. Unfortunately it coincided with the gap between exposures which, by necessity, is at least 2 seconds. This allows for the camera to fully process each exposure and if not included results in dropped frames.
