gauged sky darkness

It was clear so I decided to do an assessment. Medium seeing conditions. The neighbour upstairs had their porch light on illuminating some of the trees. Not truly dark in the backyard unfortunately.

Submitted my data to the Globe At Night site (record 14350).

sketch of Pegasus and the faintest stars I could see

Sketch of Great Square and Pegasus. Could see between magnitude 4.5 and 5.5. I.e. a handful more stars than the "less than" 4.5 chart. SkyTools says some of the stars I spotted are mag 4.7 and 4.8.

I also spotted Mars down low, mingling with the trees. But still bright, orange, sparkling.

I was surprised to see meteors. Three Draconids. All short and fast. The third was extremely bright, blue white in colour.
