sou21.png is a plot of four quantities the preceding evening (solstice day), with another PV panel and manual readings (Tomas Miler). sou21r.png shows the suitability of measuring current as a proxy for illumination.

On June 28, I bought a new small (0.01 m2) PV panel with a maximum voltage (full sunlight) almost 4.5 V. Using it, the minima during clear nights are just slightly below 1 mV, enabling measurement sensitivity of almost ten per cent. It is a good device to monitor clouds -- any clouds mean more light then that corresponding to 0.9 mV.

Actual night plot, from noon to noon, is updated 11 times an hour as night.png. Yesterday and before, the files are named yymmdd.png or yymmdd.txt.
