 A meteor travelling downwards, about 60 degrees below horizontal, bulges along the path caused by the frame refresh rate of the camera.

Calling astrophotographers!!! Garith Yang from UCL is conducting a research study into how aircraft and satellites intersect with astrophotography practices and how they shape a photographer's perception of the night sky. Take part by filling in this short questionnaire: tinyurl.com/yncd593j

I don't take it for granted; and it is a rich blessing. No matter what the day brought me, good or ill, it's done. Time for sleep.

We don't always live like this, just trying to move house whilst keeping the rest of life flying along.

For bonus points, steam vegetables over the cooking pasta.

I put half the water in a pan, the other half in s kettle. Bring both to the boil, which as the mass of water is divided between two heating devices, is quicker. Salt the water in the pan, add water from kettle. Once boiling furiously, add the pasta, reboil, cook al dente.

Impressive track-stacks from our #GMN/#UKMeteorNetwork #RaspberryPi #MeteorCameras in #Oxfordshire 13/14 Dec '25. The satellite/aircraft trails are not counted as meteors; they were just in the frame at the same time as a meteor occurred #Geminids #Geminids2025 #MeteorShower #GeminidMeteors

Two bright meteors in front of a tight comb of satellite trails, almost like Lissajous figures.

Satellites and a couple of meteors. It is getting out of hand.

Australia has so much solar that it's offering everyone free electricity Australia's extensive solar power penetration makes so much energy that the government wants to offer free electricity at peak hours.

Australia has so much electricity from solar power that it is going to start offering free electricity to everyone for at least three hours during the day as the wholesale price of power goes negative
