ANALIZA VATRENJAKA IZ OPAŽANJA HRVATSKE METEORSKE MREŽE

Sprites are optical phenomena belonging to the category of transient luminous events. They were observed using cameras of the Croatian Meteor Network. The sprite images extracted from the recordings from cameras located in Rijeka and Višnjan were analysed using two methods. Sprites recorded on the night of 2017/05/31 at 21:46:18.781 and 22:03:27.299 only from the camera in Rijeka were analysed using the single-station analysis method. This method works on the assumption that sprites occur directly above the parent lightning and uses the lightning strike location provided by the Blitzortung website together with camera recordings from one station to make the spatial positioning of the sprite possible. Sprites recorded on the night of 2017/05/31 at 21:57:44.376 and 22:07:16.440 from both cameras in Rijeka and Višnjan were analysed using the double-station analysis method, which is based on the lines of sight method. Both double-station sprites were also analysed using the single-station analysis method. The resulting heights and lateral distances were compared. It was concluded that this method of single-station analysis may provide a good estimate of the sprite location in case of small lateral distances between the sprite and parent lightning, while in other cases, errors may be significant. The double-station analysis method is preferred whenever possible, as it is mathematically exact and the errors arising from it depend only on the quality of the observation data.Rad predlaže novu metodu analize vatrenjaka opaženih sa samo jedne stanice, koristeći se pozicijom munje kako bi se odredio prostorni položaj vatrenjaka. Valjanost metode provjerena je određivanjem visina vatrenjaka. Dobiveni rezultati podudaraju se s rezultatima koje su prethodno objavili drugi autori. Udaljenost vatrenjaka od odgovarajuće munje izmjerena je za vatrenjake opažene s dviju stanica istodobno te nije zanemariva
