In the afternoon of the 3rd of September, a strong storm broke down in central Italy with very violent electrical events. Tens of thousands of lightning strikes the peninsular skies while our meteor scatter station at the APA Latina observatory was active. At that time the GRAVES transmitter was not in operation (perhaps […]

On June 14th APA radio meteor scatter station detected a persistent and widespread “cloud” of debris for about 75 minutes after the 20:30 UTC. In the video below is it possible to see how the backround noise rises highlighting the reflection of the timed GRAVES transmitter carrier. http://www.ik0vve.net/wp-content/uploads/2019/06/Nube06_19.mp4 In the next image is […] From the APA-LAN observatory it was possible to record a nice meteor outburst last night, this was confirmed also from IMO members who posted some pictures of the event. In the images that follow is possible to compare the last past 5 days until the Draconids peak. The presence of […] It’s more than three years that I monitor VHF for meteor scatter signals thanks to the French GRAVES radar near Dijon. This is a bistatic radar that transmits a CW signal at 143.050. With a simple radio system is possible to receive the radar signal reflected by the meteors ionized plasma that these […] Tra qualche giorno la stazione spaziale cinese Tiangong-1 entrerà nell’atmosfera terrestre disintegrandosi, speriamo per gran parte della sua mole. Per l’occasione ho predisposto il mio sistema per la ricezione meteor-scatter VHF tramite il radar GRAVES, in modo da provare a ricevere un’eco radio prima della totale disintegrazione della stazione. In questo caso, visto che attualmente […] Here some of the best images from Orionids shower of this year and a time lapse video of the shower period: Friends link about this event: IU3IOU Giorgio IK0OZK Renato […] Questi giorni si avvicinerà alla Terra l’asteroide 2012 TC4 ad una distanza veramente minima per un oggetto spaziale, domani alle 7:42 ita il picco di massimo avvicinamento. Con quasi le stesse modalità del sistema meteor scatter sto provando a ricevere sulla frequenza del GRAVES l’eco dell’asteroide che transiterà a circa […] Solo ora sono riuscito a terminare la stesura del report sulle Perseidi 2017. Purtroppo ancora ho problemi nel far lavorare assieme SpectrumLab con RMob con la conseguenza che i dati degli eventi non si distribuiscono per ore ma sono raggruppati in grossi “ammassi”, solo grazie all’indispensabile e preziosissimo aiuto del mio amico e […] What follows is the capture of ISS (International Space Station) passing over my coordinates this morning. The fast descending signal is the trace of doppler echo from GRAVES signal. The yellow circle shows where the ISS was about during the capture and the red arrow the direction. […] |
