The BuioMetria Partecipativa Map now embeds also readings by Unihedron

A sky quality meter in the process of being “passed” as a relay baton between two characters in the network (Dec. 2016).

After switching back on the interactive BuioMetria Partecipativa map during the twentieth edition of “M’illumino di Meno”, we are gradually adding layers to the canvas that we would like to use over the coming months to trigger actions about light and darkness.

After the CNR IBE monitoring network, we have reloaded the data collected by Unihedron, i.e. the producer of the “Sky Quality Meter”, which we renamed as “buiometri” for our Italian communities.

The new map is available at

We would like to recall that the Sky Quality Meter is not the only type of sensor existing for the measurement of night sky quality. In fact, with the BuioMetria Partecipativa since 2011 we have conducted various intercomparison and cross-calibration experiments. However, the SQM still remains as the most widespread entry-level sensor, plus it is the one which we have historically used as a liaison between the various participants to the buiometria measurement campaigns.
