Hi All,Just a heads up on this potential observing opportunity.IF LandSat 9 launches on schedule tonight then there is a chance that the de-orbit burn of the Centaur upper stage may be visible over the UK at around 21:10 UT (22:10 BST).The satellite is launching southwards from Vandenburg AFB. Passing over Antarctica it will then proceed northwards. From the UK it will rise above the SE horizon IN SHADOW (hence not visible) at 21:04 UT, eventually passing into sunlight near Polaris at around 21:10 UT.As ever with these things, there’s always a degree of uncertainty but if visible, it will look somewhat comet-like – just moving across the sky at the same sort of speed as a satellite.Clear Skies – and thanks to Cees and Marco for the heads up!!William

Just seen it and imaged with samyang 85mm F1.4 800iso 4.00 sec rather over exposed as was expecting something around 2 nd Magnitude.. Just absolutely took me by surprise and brilliant double delta shaped plume. Will process images and post tomorrow on Members pages.27 September 2021 at 11:08 pm #584739john simpsonParticipant
Many thanks for your post – amazing view, even through trees.28 September 2021 at 1:28 am #584740Nick JamesParticipant28 September 2021 at 1:43 am #584741Gordon MackieParticipant
I was out imaging the Milky Way and luckily spotted this. I only found out afterwards that it was the LandSat 9 satellite. It was very bright and obvious, and moved across the sky quite quickly. So to keep the exposure as short as possible (to minimise motion blur) I put the ISO as high as it would go on my camera (Canon 760D, ISO12800, 1 sec). The end result isn’t the best quality, but it captured a really memorable moment.28 September 2021 at 2:22 am #584742Grant PrivettParticipant
Wish I had seen this. Looks impressive. Do let us know if you get another headsup!28 September 2021 at 12:03 pm #584743Neil MorrisonParticipant
Images from last evenings event . Initially set up the Tripod mounted Camera with Polaris Centre Frame. However the Rocket Plume just sprang into view much lower than Polaris so a mad scramble to move the equipment to a spot in the garden a few feet away with a lower Horizon. Hence some tripod shake . An amazing sight over in a brief minuite
