Vu la couverture nuageuse et\/ou le brouillard, il a \u00e9t\u00e9 difficile d’observer les \u00e9toiles filantes ‘G\u00e9minides’ la nuit pass\u00e9e.
\nMais j’ai pu utiliser une antenne radio du r\u00e9seau BRAMS pour capter l’\u00e9cho que font ces grains de poussi\u00e8re en rentrant dans l’atmosph\u00e8re.
\nVoici un visuel d’une capture faite cette nuit durant 10 minutes apr\u00e8s 1h du matin.
\nLes lignes verticales pointill\u00e9es sont espac\u00e9es de 30s.
\nLa ligne horizontale (1000 Hz) est la fr\u00e9quence de la balise install\u00e9e \u00e0 Dourbes.
\nLes traits verticaux et d’autres en forme de tire-bouchon repr\u00e9sentent les \u00e9chos; il y a du monde ! \ud83d\ude09
\nLa 2\u00e8me photo repr\u00e9sente le \u00ab\u00a0spectrogramme\u00a0\u00bb de ce matin vers 10h45 et il n’y a presque plus de traits verticaux – preuve que le maximum est pass\u00e9 – mais beaucoup plus de traits courbes => ce sont les \u00e9chos dus aux passages d’avions entre Dourbes et chez moi.<\/p>\n
