Time-lapse of AARTFAAC detections of radio meteors in Perseids 2020
<p>LOFAR AARTFAAC images (integrated over all observing bands) during the Perseids meteor shower in the night 2020 August 12 --13. The large-scale diffuse emission is the Galactic plane. The brightest radio sources Cassiopeia~A and Cygnus~A have been subtracted, sometimes leaving some artefacts. In red, trajectories as computed from the CAMS BeNeLux optical observations are overlaid.</p> <p>Observing frequencies were in the range 30 to 60 MHz.</p>
Perseids 2020 over Dark Sky Park Poloniny, by Tomáš Slovinský, Slovakia
<p>Second place in the 2021 IAU OAE Astrophotography Contest, category Meteor showers.</p> <p>A meteor shower occurs when the debris originated from comets or, on rare occasions, from asteroids enter the Earth’s atmosphere at high speed, leaving behind beautiful tracks in the sky due to friction with the atmosphere. This all-sky image taken in Slovakia in 2020 shows the Perseid meteor shower in a vivid way so one can really see the Perseids appearing all over the sky. This meteor shower is named so because the radiant point (the point on the sky where the meteors misleadingly seem to originate from) of the Perseid meteor shower is located in the constellation Perseus. This is a very prolific meteor shower, and a very popular phenomenon that can be observed from mid-July until mid-August, when the peak of activity happens. This is associated with the comet 109P/Swift–Tuttle, as Earth's orbit around the Sun crosses the debris left behind by this comet. This kind of image is very useful for full dome projections in planetariums, beautifully showing the Milky Way, our home Galaxy.</p> <p>Credit: Tomáš Slovinský/IAU OAE</p>

Raw I/Q capture of GRAVES reflections caused by 2023 Perseids
<p>Raw I/Q capture of the radar reflections originating from the <em>Grand Réseau Adapté à la Veille Spatiale</em> (GRAVES) radar in the 143.050 MHz frequency, and caused by the meteor ionisation trails during 2023 Perseids meteor shower. The file format is 2 x float32 (cf64), little endian and the sample rate is <span class="math-tex">\(f_s=1.92\text{ Msps}\)</span>.</p> <p>The capture was obtained from an <a href="https://es.aliexpress.com/i/1005003181244737.html">AntSDR E310</a> in 2r2t mode, tuned to 143.3 MHz. The antenna consisted of a minimal array of two <span class="math-tex">\(\lambda/2\)</span> vertical dipoles, with a <span class="math-tex">\(\lambda/2\)</span> spacing between both, with a design frequency of 143.050 MHz. The location of the antenna was 40.45342176913288º N, -3.408497019619436º E</p> <p>The file was produced with SigDigger's "Pluto/ANTSDR 2RX combined source", provided by the <a href="https://github.com/BatchDrake/AntSDRPlugin">AntSDR plugin</a>. This custom signal source modulates the samples of RX1 and RX2 by <span class="math-tex">\(-f_s/4\)</span> and <span class="math-tex">\(f_s/4\)</span> respectively, and sums both. This results in a spectrum that, once visualised from SigDigger, seems duplicated around the central frequency.</p> <p>This representation enables simple manipulation of both coherent channels with the existing software infrastructure: if we wanted to compare the phases of a channel at frequency <span class="math-tex">\(f_0\)</span> coming from both antennas, we would see the signal coming from RX1 at <span class="math-tex">\(f_0-f_s/4\)</span> and the signal coming from RX2 at <span class="math-tex">\(f_0+f_s/4\)</span>. It would suffice by multiplying the samples by two NCOs that cycle over phases <span class="math-tex">\(0,\pm\pi/2,\pi,\mp\pi/2\)</span> and applying an appropriate low-pass filter and decimation to the output of both.</p>
