Sky Quality Meter – Astrofili Lessinia Orientale

Lo Sky Quality Meter è uno strumento utile a misurare la luminosità del cielo. L’unità di misura utilizzata è la magnitudine per arcosecondo quadrato. Maggiore è la magnitudine rilevata, minore sarà l’inquinamento luminoso presente.

All’Osservatorio abbiamo un sensore installato sulla cupola che rileva questa lettura ogni 5 minuti e la manda su un server dove viene elaborata e graficizzata. Il grafico sottostante viene aggiornato continuamente durante la notte e viene azzerato al crepuscolo quando iniziano le letture per il giorno successivo.

Letture medie e massime ultimi 30 giorni

Le letture vengono rese disponibili anche in formato Excel a partire dalle 7:45 ogni mattina, insieme ad altri parametri. Le colonne di questo file vanno lette così:

MPSAS:	Magnitudine/arcsec²
NELM:	Magnitudine stellare teorica visibile ad occhio nudo
Temp:	Temperatura del sensore
EncOffset:	Correzione alla magnitudine dovuta alla perdita di luminosità per la copertura del sensore
SolarAlt:	Altezza del sole in gradi decimali rispetto all’orizzonte
LunarAlt:	Altezza della luna in gradi decimali rispetto all’orizzonte
LunarPhase:	Fase lunare (0=luna nuova, 1: luna piena)

Letture SQM delle ultime 24 ore
