(This is a composite photo of my shot (left) and one taken from ISS (right) most likely) We have all been desperately waiting for the launch of HTV-7 cargo vehicle, which was due originally on 10th September but delayed a couple of days for various reasons. My evening ISS flybys just started in London and the delay turned out to be very beneficial for me. It coincided with the beginning of the flybys, so this way I had the opportunity to see and photograph both objects. And I just did that!! 😁
I had to use different camera settings for HTV-7 because this object is much smaller and fainter compared to ISS. But I had some pervious experience with Cygnus and Progress cargo crafts. What turned out to be the case is that HTV-7 flared. Twice! We have been observing HTV for the third night in a row and it just kept flaring. I only recon it is spinning at a very slow rate… Here are my best shots of HTV-7. Most of the frames were overexposed partially due flare effect, luckily I managed to capture a handful of good shots too. The predicted brightness was mag. +2.5, but it was brighter than that!
Distance of HTV-7 – well good question. It means to flyby on a much lower path with a max. elevation of 40 degrees. But it caught up with ISS quite a lot during the past day and it followed the station almost exactly on the same fly path. ISS was at 440km of distance from my location at its closest point, so HTV-7 should have been at a similar distance. But I think HTV-7 was not at the same altitude as ISS for safety reasons, most likely 100km lower at around 300km above Earth and maybe 340km away from my location.
