The last few days we have been receiving a lot of rain in Colorado. Ergo, it is cloudy most of the time.
As I finished building my Diptych Portable Sundial, it was a cloudless, sunny sky.
I took my portable sundial outside and set it up on the patio table in my backyard. This is the first time I am using my Diptych Sundial.
I used the offset on my compass to align the Sundial with celestial north. I used a bubble level to level the sundial.
Note, when your cell phone is near a compass, it will effect the direction it points. In the above picture, the compass was perfectly aligned with celestial north. Only when I brought my phone close to my setup to take this picture, you can see a slight deviation in the compass's pointing due to the electromagnetic effects the cell phone produces.

Don't worry about the compass being slightly off in this picture. Before I brought my cell phone close to my table to take this picture, it was pointed directly at the celestial north.
