Official launching of FRIPON

Observatoire de Paris – 61 avenue de l’Observatoire – 75014 Paris – France – www.obspm.fr Tuesday May 31st, 2016 marks the official launch of FRIPON, a unique interconnected network to search for meteorites. Eventually comprising 100 cameras spread out all over France, FRIPON introduces a night and day 360° watch of the sky. Born from the joint scientific expertise of Observatoire de Paris, of Muséum national d’Histoire naturelle, of Université Paris-Sud, of Université Aix-Marseille and of CNRS, this network aims to detect meteorite falls, measure their trajectories and estimate their strewnfields so that field search campaigns can be organized.

Recording and comparison of the lightning spectrum

At the Valasske Mezirici Observatory are currently operating three cameras equipped with a spectroscopic system. The main goal of these cameras is recording the spectra of meteors and thus identify the chemical composition of meteoroids and also emission lines of elements contained in the Earth’s atmosphere. However, during the occurrence of storm activity the objective of the observations may change and spectrographs can record the spectra of electrostatic discharges – lightnings. This was also during a thunderstorm in the evening on June 19, 2016. Jakub Koukal¹, Martin Ferus², Libor Lenža¹ ¹ Valašské Meziříčí Observatory, Vsetínská 78, 75701 Valašské Meziříčí,...

Meteor Activity Outlook for 25 June-1 July 2016

During this period the moon reaches its last quarter phase on Monday June 27th. At this time the moon will lie 90 degrees west of the sun and will rise between midnight and 0100 local summer time for most sites located in mid-northern latitudes. The half-illuminated moon will interfere with meteor observing, but to a much lesser degree than when near its full phase. Toward the end of the period the waning crescent moon will rise during the late morning hours allowing allowing most of the night to be free of lunar glare.

Fireball on June 22nd, 01h14 UT recorded by 18 video stations of FRIPON network

A bright fireball was largely recorded by the new FRIPON network, as it was recorded by 18 video stations (out of more than 60 dispatched all over the French territory), and 2 radio receptors (Orsay and Orléans, that are currently the only ones installed). The fireball appeared on June 22nd, 2016, at 01h14 UT. It was recorded on 2 radio receptors located in Orsay and Orléans. And it was also visually observed by people who reported it on the IMO/AMS fireball report platform. Calculations performed with FRIPON team software indicates that the meteor luminous path started between Chambéry and...
