Fascinating observation and photo documents.

Cool, Andrew, great details. Here's even an English source about that launch https://www.untvweb.com/news/china-l...-3-satellites/

And this one explains the booster 3 stages of the rocket https://www.nasaspaceflight.com/2018...long-march-3b/
"The first two stages, as well as the four strap-on boosters, use hypergolic (N2O4/UDMH) propellant while the third stage uses cryogenic (LOX/LH2) propellant."
On the side: that the circle stayed in shape over the whole time you saw it means that no debris accompanied the "explosion" which could have deformed the exhaust cloud at the very beginning?


Do you remember this one from Oct 2017 in Russia? In the spaceweather.com article there's a link to the photographer's VK-page, the Russian Facebook. Beautiful captures of the blast, with an aurora, too. http://spaceweather.com/archive.php?...h=10&year=2017
You can click through the whole sequence.

Object near Canopus

Hi Lewis,
I saw this as well from regional Qld but was reluctant to post my experience without photographical evidence in case people thought I was .
I can however offer a detailed description of what I saw visually. I had just returned my scope to the home position & about to pack up when I noticed the object below & to the right of Canopus, I noted the time was 12:42. It was easy to slew my 127ED with the 24mm 82deg eyepiece still in it & still focused across to the object & track it using the hand control. I was afforded a very decent view & maintained very good visual contact with the object as it moved towards the horizon in the SE. At the centre of the luminous glow there was a pinpoint sharp object similar to how a satellite would look as it passes through your FOV , but this was brighter & distinctly red in colour. As I continued to follow it a satellite did indeed pass through my FOV on a path at right angles to the object for a convenient comparison, this highlighted the fact it was moving much faster & was larger & brighter than the satellite. The glow around the object I could only describe as nebulous & the whole image remained consistent until it disappeared from view. I must admit I felt a bit of a chill down my spine at the time after witnessing such a phenomenon. Do we have reasonable explanation for it yet? BTW I'm expecting a visit from the MIB
Clear skies,
Tony
