Radar observations of the Lyrid meteor shower at Budrio

  • Published:
Il Nuovo Cimento C

Summary

Radar meteor observations carried out at Budrio (Italy) during the Lyrid meteor shower period in 1983–1985 are analysed and discussed. Lyrid activity is obtained applying to the observations a range distribution method. The maximum of activity is found at solar longitude 31.3° (epoch 1950), the duration of the shower between quartermaximum points is about 2 days and the overall Lyrid activity approximately 6 days.

Riassunto

Si analizzano e si discutono i risultati delle osservazioni radar di meteore effettuate negli anni 1983–1985 a Budrio (Italia) nel periodo dello sciame delle Liridi. L'attività delle Liridi è ottenuta da un metodo che fa ricorso alla distribuzione delle distanze, dei radioechi. Il massimo dell'attività è identificato alla longitudine solare di 31.3° la durata dello sciame valutata tra punti ad un quarto del massimo è di circa 2 giorni, e l'attività complessiva delle Liridi risulta essere approssimativamente di 6 giorni.

Резюме

Изучаются радиолокационные наблюдения метеорного потока Лирид проведенные в Будрио (Италия) в 1983–1985 гг. Активнссть потока получена методом распределения дальностей радиоэхо. Максимум активности наблюдалось на долготе Солнца 31.3° (равноденствие 1950), длительность повышенной активности между пунктами с 1/4 максимальной численности получилась около 2 дней; Лириды можно выделуть из спорадического фона в течение приблизительно 6 дней.
