Algorithm for accurate alignment of spectrograms by GPS time marks was improved. Now it also aligns the records with lower quality of the measured signal. Therefore comparison image now contains data from more stations.
Yesterday (25. 11. 2017) Bolidozor was presented at the annual meeting of the south-czech branch of Česká astronomická společnost at Hvězdárna prof.Františka Nušla při DDM v Jindřichově Hradci. Participants learned about the state of Bolidozor, about storage and processing servers and about new visualization tools.
British photographer Ollie Taylor Photography photographed from the Italian Dolomite fireball, which the Bolidozor network observed. Information about our detection is mentioned in the previous post. This beautiful shot was chosen as Astronomy Picture of the Day (APOD)

Ok, so i have just come down from Passo Falzarego, I had been up there shooting the dipper at twilight, then... this happened!!!
So lucky to have caught it as my exposure times were only 8 seconds, so cool how it dipped below Ursa Major, and the pink hue from twilight still there!
Honestly looked so low, and bright, and huge!!
Blown away, huge thanks ESA, AMS, NASA for the exposure you guys generated on this...
Bolidozor, radio bolid detection network, today (14. 11. 2017) detected a fireball at the same time as many optical observers according to International Meteor Organization reports. At picture below, you can see aligned spectrograms from 3 stations by time (by GPS marks).
There is a big chance that it is the same fireball.

Bolidozor team was at IMC 2017. Here is short evaluation of the event.
Two weeks ago, the 2017 IMC was organized in Petnica, Serbia. Small overview of what happened there!

When you open multibolid detail page of some processed bolid you can see time aligned spectrograms from multiple stations alongside.
Po otevření detailu multibolidu, který byl již zpracovaný, můžete vidět časově zarovnané spektrogramy daného meteoru z více stanic vedle sebe.
The fundamental principle of Bolidozor network is the radio detection of meteor ionized trails. Meteor trail may reflect the radio waves from the transmitter to the receiver. Reflections can last from a tenth of a second to a few minutes. The received signal characteristics are related to physical parameters of the meteoric event giving a possibility to estimate a meteor trajectory.
Nový způsob časové korekce záznamů zlepšil kvalitu vyhledávání vícestaničních rádiových bolidů..
The new time correction method of recorded data significantly improves the automatic radio muli-station detection of bolides.
