This is a video of one of my contributions to a London Composers Forum concert held at the 1901 Arts Club earlier this year, where I performed a sub-cycle of six of my Preludes for piano. It is a very nice venue with a nice piano. youtu.be/ng241OcFFT0
First Jupiter images of this apparition, monochrome, infra-red and red. Seeing was quite good before dawn on Wednesday. Great Red Spot is to the lower right (bright)

I will be performing some of my Preludes for piano at this concert on Monday evening in London. Full details and tickets available here: 1901artsclub.com/27-mar-2023…

El pasado martes astrónomos de la asociación WOLAS nos visitaron. Vimos la Luna, Júpiter, Marte y el paso de la ISS.🌓🌝🌓
Gracias a @StagLaneObsy David Arditti , Stewart Coulter, y Martin Williams @ISAartsUK @AccEducativaExt @consejeriauk
A single frame from my video of the occultation of Mars at 5:00 this morning. Taken with a 14-inch SCT and ASI 120MC-S camera.
I am sitting in my warm room waiting for the occultation of Mars. I tried taking a high-resolution image of Mars but the result is not great as seeing is poor. You can, however, just see Olympus Mons lower left. I will reduce the image scale for the occultation.

The recognisable face of Mars - The V shaped Syrtis Major. This was the subject of the first drawing of a feature on an other planet by Christian Huygens in 1659
Mars on Wednesday morning in fair seeing, with Sinus Meridiani near the centre of the disk, Syrtis Major on the terminator, and cloud over the N pole (S up).
Additionally they have major uses in astronomy as 1) Dust seals for telescope drawtubes, and, 2) with a small hole made in them, collimation tools.
These containers were some of the greatest storage containers for little things that you don’t want to lose ever

Some changes visible on Mars in 3 days. On October 3 western Solis Lacus was still dust covered, but dust retreated by October 6. On that date also the NW tail of Mare Acidalium showed dark at the terminator, the rest being affected by the dust that spilled over Chryse-Xanthe.

Last month my friend @Spicey_Spiney, a @RoyalAstroSoc Fellow and winner of the @BritAstro Sir Patrick Moore prize for contributions to astronomy outreach, tweeted a video of a meteor trail which somehow got flagged "intimate". She's still suspended. @TwitterSupport can you help?
2 images of Jupiter a month apart, showing different sides. The one showing the Great Red Spot was taken this morning. The GRS it looks nothing like it did even last year, smaller than it has ever been before in telescopic history.
Includes my article '5 Observing Projects for Saturn at Opposition'.

A big thank you to @conselice @julianonions @StagLaneObsy @BritAstro @npae @UoN_Physics @SocHistAstro @crystal_nebulae and everyone involved in today’s BAA summer meeting held at the @UniofNottingham
Here are spots visible on the Sun yesterday adfternoon. The 'semolina' effect of the top of the photosphere, caused by the rising columns of fluid, can be seen, and the bright photospheric network round the spots.
Simple shot of the Moon, taken in one exposure with a 4-inch refractor on 14 March, presented normally, and with over-saturated colour. It's clear how the Mare Tranquillitatis (just above centre right) is bluer than the other basin maria because it has more aluminium in the soil.
