Draconids 2018 meteor shower

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 vertical lines is very […]

APA – lan|Meteor scatter antenna improving

After about a month and a half from the beginning of the meteor scatter project with a satisfactory success, we wanted to make a small improvement to the reception system by doubling the antenna. From the beginning the antenna was a four element 1.5 lambda boom length with a gain of about 8.5 dbd. We […]

The project: how to “show” the falling stars to the blind

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 objects create […]

Quadrantids Meteors shower

A very big echo captured during this meteors shower event:

Almost a 2 minutes long echo with a very strong reflection signal. The same signal was received from other GRAVES friends.

GRAVES TX power down.

Suddenly today at about 10:20 UTC no more echoes from GRAVES transmitter have been received at my meteor receiver. A Christmas time maintenance?

Shortly before a strange activity has been captured from my receiver some Hz upper the usual meteor frequency.

Meteors Radar

In these last days I focused my free time to meteors radar by French GRAVES VHF Radar transmitter. The new page is here: Meteors Radar.

On this page you can find a 3 minutes auto-refresh picture almost real time. Just under a statistics image of received meteors signals.

At the moment the system is composed by […]
