The Tianwen-2 spacecraft seems to have performed another manoeuvre earlier today (22 June). These observations are done by @amsat-dl.org with the 20m dish in Bochum.

Measuring Radio Recombination Lines (RRL) with the Dwingeloo telescope (@radiotelescoop.bsky.social), in the Omega Nebula (M17/W38).

On the occasion of the @unesco.org International Day of Light, we created a 'light painting' using the Dwingeloo Telescope by mounting a light bulb at the focus for half an hour. #lightday2025 @idlofficial.bsky.social

A bit late, but here is some additional analysis of the Earth-Venus-Earth radar experiments with @radiotelescoop.bsky.social from March 22nd, 2025. It takes the 4 recordings at the Dwingeloo and Stockert telescopes and searches in Doppler frequency and Doppler rates for the radar reflections.

We used the historic Dwingeloo telescope to bounce a signal off the surface of Venus, and receive its echo! This marks only the second time that amateurs have achieved an 'EVE' (Earth-Venus-Earth) bounce. Venus was about 40 million kilometers from Earth. www.camras.nl/en/blog/2025...
