Two pictures of my apple tree; one on a cloudy day, the other taken at 8pmJanuary 2. Reflection of lamplight in one may give it away. A moonbright night.

Here they are.

Measured CO2 in the four rooms of my house where I spend the most time bedroom 578, sewing room 504 family room 540 and kitchen 540 New Brunswick, 🇨🇦. Looks like I need to spend less time sleeping (where I have an air purifier) and more time sewing.

This is my second box using the same fan but new filters. Seasonal background extra.
