BTW, here is another recent digital treatment of that legendary 1895 movie clip: https://www.youtube.com/watch?v=Zlc6H5dtdLs … - wonder how much (manual) effort is involved in this ... and whether we might soon / one day see a lot of poor quality early space age footage in a new way. h/t

Here is the key slide from the AAS presser with three numbers to ponder. (This refers to unmodified Starlinks in operational orbit and attitude, not the even much brighter freshly launched trains.)pic.twitter.com/UL7JGOuBKA

The 3rd Starlink chain two weeks after launch, rising from the horizon on 21 January (see http://bonnstern.wordpress.de/2020/01/22/die-dritte-starlink-kette-uber-heisterbach … for full context) - I was honestly shocked how bright they were already at very low elevation, in spize of the large distance and atmospheric extinction.pic.twitter.com/LmFkOR5Sro

The respective study is discussed in the second presentation of the January 8th AAS press conference https://www.youtube.com/watch?v=QM1eh7nq24I … (the speaker also sent me his much longer presentation from the earlier technical session; they've done a lot of modelling but much more needs to be done).

@dsfpspacefl1ght Space history must be hard. On German TV they just showed the 2015 episode on the Mir fire from the Discovery Channel's "Secret Space Escapes" https://www.youtube.com/watch?v=owWfnUy0KK8 … - which systematically writes the German cosmonaut R. Ewald out of history who was also aboard.Prikaži ovu nit -
While
#Betelgeuze continues a slow fade (here a cloud of amateur observations since beginning of the year), professional astronomers are observing its *resolved* disk and surroundings: https://twitter.com/Astro_MiguelM/status/1224426557017673728 … - the data reduction is very complicated, though, so ... patience. ;-)pic.twitter.com/aTSQKlf7Jq

This is from https://www.youtube.com/watch?v=HwRdcv8azvk … which *cannot* be from 1947 as e.g. escape seat testing for the F-104 is shown ... which was *designed* in 1952 only. Please find out from which year this really is.

Hmm, die Quelle https://www.youtube.com/watch?time_continue=261&v=HwRdcv8azvk … behauptet ebenfalls von 1947 zu sein - kann aber nicht stimmen, weil z.B. die F-104 überhaupt erst 1952 *entworfen* wurde ...

"Steady" is in the eye of the beholder ... see the bottom of https://skyweek.wordpress.com/2020/02/01/allgemeines-live-blog-ab-dem-1-februar-2020 … for several plots. (And here's a VOL-only 100-day plot - he's been on Alf Ori *way* longer than PTOB, for many *years* actually - with a clear slow-down of the trend.)pic.twitter.com/wRU0dx2qgs

More fun with
#Betelgeuse light curves up to today for a review of the situation in https://skyweek.wordpress.com/2020/02/01/allgemeines-live-blog-ab-dem-1-februar-2020 … (scroll all the way down): slightly fading again to between 1.55 and 1.60 mag. now after a ~1.5 mag. quasi-plateau in mid-January? So much excitement, so much noise ...pic.twitter.com/AWR8ks6x9B

Wanna see one more scary / fascinating / shocking video of the fresh
#Starlink chain #4 (from New Zealand)? Comes with sweet music:https://www.youtube.com/watch?v=4LzkYrrj5Wg …Prikaži ovu nit -
Can we invert that problem? Like predicting when we in Europe will have the next chance to see a satellite train that is only days old (as was the case after the May 2019 launch)? As much as I'm worried I'd like at least to see something like https://www.youtube.com/watch?v=MUoavxYlrgA … one day ...

Processed screenshots from the NASA webcast of the
#Cygnus departure - cropped, gamma-corrected and de-distorted (which is sadly still necessary at times; even in 2020 NASA still can't tell 4:3 from 16:9 video formats reliably ...) when needed.pic.twitter.com/wPpI9LSwur

Seconds before the 2nd stage shut down, the video feed terminated and the kick stage separated - everything else is 'dark' now ...pic.twitter.com/DV3VVjur5A

There goes the 11th Electron! And just before from another camera angle we saw tons of sheep grazing in front of the rocket. Welcome to New Zealand ...pic.twitter.com/Skq7afFLwY

First visual - actually a cool real-time movie clip - of the fourth
#Starlink chain I've seen in which the satellites launched on the 29th are still pretty close to each other:https://www.youtube.com/watch?v=MUoavxYlrgA …Prikaži ovu nit -
Now that neither Betelgeuse has exploded nor the two satellites have collided how about this scenario? Seen last night in a

Here is the old infrared observatory IRAS gliding happily - if defunct for decades already - over the California sky, three hours after the close encounter with that other satellite:https://www.youtube.com/watch?v=WrsdcPBWx3w …

The past four weeks of
#Betelgeuse photometry from the AAVSO database: essentially a plateau around 1.5 mag. or maybe a very slow fading - whether the latter got a bit steeper in the past week is still TBD and may not be significant. (And certainly no brightening in sight yet.)pic.twitter.com/n3D6KC1PVk
