We had to observe low above the horizon (2˚) making calibration hard, but it's still quite bright - a few Jansky, as was noted in Astronomer's Telegram 18003 on 24 August. 091
Reposted by @tammo80.bsky.socialCees Bassa @cbassa.bsky.social · 18/08/2026Back in 2019 we, as radio amateurs, used an amateur radio payload with a camera on board the Chinese DWLSP-B lunar satellite to take a similar picture of the July 2nd eclipse. Our initial posts on twitter are gone, but a write up is available at destevez.net/2019/07/resu... 282
tammo80.bsky.social @tammo80.bsky.social · 15/08/2026M'n #meteorencamera heeft dit jaar weer een goede oogst aan Perseïden: 470 stuks. Door alle beelden te projecteren op de hemel op één tijdstip zie je mooi dat ze inderdaad uit een punt lijken te komen (in het sterrenbeeld Perseus). #globalmeteornetwork 000
tammo80.bsky.social @tammo80.bsky.social · 22/06/2026The 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. 071
tammo80.bsky.social @tammo80.bsky.social · 26/05/2026You should update to the newest SatDump, which would get demodulated data ;) Thanks @aang23.satdump.org ! 300

tammo80.bsky.social @tammo80.bsky.social · 20/04/2025Great work! This is why we put our IQ on the web :) One remark on why Dwingeloo is less sensitive: we have a relay in front of the first LNA, because Dwingeloo also transmits in experiments like this one. Apart from that, we may also need a better LNA. 031

It takes the 4 recordings at the Dwingeloo and Stockert telescopes and searches in Doppler frequency and Doppler rates for the radar reflections. 2155
Reposted by @tammo80.bsky.socialRadiotelescoop Dwingeloo @radiotelescoop.bsky.social · 24/03/2025We 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... 66523
