There is a IFTTT routine that sets today's NASA pic as your Android wallpaper everyday.

I maybtry one later - my guess is wget and dconf should do it easily enough.

I just nicked something off GitHub I think. Minor complication was that I'm using i3wm. But I haven't touched it for years to be honest

Noctilucent clouds! They've been visible the past few evenings apparently

They're pretty rare and quite mysterious. Were never observed before 1885 and no one is quite sure how they form; may be something to do with rocket launches or meteors.

Was in bed and got up to close my window, but when I spotted these I had to run off to get the camera and tripod :) quite surreal to see such bright clouds at 2 AM, it reminded me a little of the aurora.

Check the timestamp.

What a glorious run of clear nights we've had. Sadly I have not been able to take advantage of them much, and they are so short. But good to see the Milky Way over the neighbour's bay tree.

Exciting - and traced back to a blazar off the shoulder of Orion

Nearly 4 billion light years away. The power of the event would have been eye watering!

Probably attack ships on fire that caused it then...

Blood moon this coming Friday / Saturday

International Space Station has been showing well this week. And Venus, Jupiter, Saturn and Mars are all visible in the evening sky.

Yep, I am out with my camera aiming to catch the ISS passing overhead at 23.13.

Venus getting very low now, but still could see Venus, Jupiter, Saturn and Mars at the same time this evening.

If you're into faint fuzzy blobs, there's one with a tail going past Capella this weekend. Comet 21P/Giacobini-Zinner is top right. Capella is red because of a filter I was using to cut out sodium streetlights.

Excellent work as ever Ludd!

What was the exposure time?

Thanks! It was 66 seconds. It's caning it across the background stars so I didn't want to try much longer than that.

Great shot, Paul. May I ask what f-stop and ISO you used?

I used to do a bit of astronomy photography years ago, forgotten most of it now.

How long will it be around for?

Thanks Sam. F3.2 and ISO800. It's around for a couple more weeks at least, I think.

Thanks. Obviously easy to find tho at the weekend as so close to Capela.

Caught a couple of man-made objects hurtling overhead this evening. An Iridium satellite and then the ISS.

Great stuff as always. How come the top one's trail seems to brighten and fade but the lower trail is more consistent?
