Er is hoge druk om AI uit te rollen & als je de Thought Leaders volgt lijkt het wel alsof je verloren bent als je niet opschiet. Ook zijn er mensen mordicus tegen, zo tegen dat ze niet met de beste kritieken komen. Hier ideeën over wat nu te doen, en wat beter kan wachten: berthub.eu/articles/pos...

AI: Overwegingen voor wie erover gaat - Bert Hubert's writings

Onlangs presenteerde ik kort na elkaar bij het Netwerk van Publieke Dienstverleners en bij de Adviesraad Wetenschap, Technologie en Innovatie over AI. In deze twee verschillende maar korte presentatie...

Slowly getting better at recognising the geo-location of home received X-band KANOPUS-V imagery, using cloud shadows to estimate latitude - 30/6 V 5: Witbank/Emalahleni, South Africa - 3/7 V 4: Al Theniah, Saudi Arabia - 8/7 V 4: Al Hazm, Yemen and Khbash, Saudi Arabia

Yesterday I took a KANOPUS-V 3 X-band pass where I recognised an area from FENGYUN 3B images I received years ago. Navodari on the Black Sea coast. Local crop, somewhat bigger area (both PSS), a MSS false colour crop and a FENGYUN 3H crop of the area an hour or so later.

Spent today X-band tracking "Le quattro stagioni" of FengYun weather satellites: 3D, 3E, 3F and 3H (and 3G) - data processing is a lot of work, so images later. First this solar FY3E XEUVI image with some nice solar flares and plasma arcs (and a cosmic ray hitting the detector)

Lots of condensation trails can be seen on this Netherlands crop from a FY3F pass @ 10:55 UTC - but if these semi circles near the middle are condensation trails, what was that pilot doing ??

From a FY3F pass @ 09:46 UTC today, a Colour Infra Red (CIR) crop centered on Greece. A vast amount of bush fires can be seen, including what looks like a big one on the Island of Chios.

Proba-3 achieves its first ‘artificial total solar eclipse’ in orbit. The mission can create these eclipses once every 19.6-hour orbit & make them last up to 6 hours. With such observations scientists will be able to answer long-lasting questions about our star 👉 www.esa.int/Enabling_Sup... 🔭 🧪 ☀️

This is an image of the Sun during an artificial solar eclipse. Against a black background, the Sun’s bright body is covered by a black disc, and light green hair-like tendrils extend from the black disc in all directions. Brighter green light peeks from behind the black disc’s edge, slowly fading towards the outer edges of the image.

Was busy with two space related activities today: 1. Receiving an X-band image from ELEKTRO-L 2 @ 14:30 UTC today (peak S/N 11.0 dB, avg 10.3 dB) and 2. Reviving a 2014 OpenSUSE VirtualBox VM for processing @science.esa.int Mars-Express data; a Nadir channel image of Phobos by the HRSC camera

Using the verywip branch of the mighty SatDump to align the METEOR-M2 4 KMSS channels of an earlier recorded pass (20250402) - a Colour Infra Red view of the Wadden sea and the Northern part of my country. Excellent job @aang23.satdump.org !

Weather satellite picture of the Northern part of the Netherlands and the Wadden sea (UNESCO World Heritage) in a so-called colour infrared composition.

I have been using some French and Dutch coastline scenery to optimise my own CADU reading/geometry correction software using a FY3F pass at 12:22 today and the CADU created from it with the unique SatDump S/W. Still some way to go, but not bad. Dotting the i's crossing the t's.

A while back I monitored the ELEKTRO-L 2 carrier 16 hours assuming its power would tell me when image transmission signal is best. Today I followed that recipe and received my first "images" of the season, far from perfect. Also noted in between images a low rate TM signal (BPSK ?)
