Visibility IV / V
Today, the morning of the summer solstice, was the milestone of a three-month solar photography project. Every week, I pick up one picture from the pictures of the east camera at the time of the sunrise. The moments of ascension described were not exactly scientifically accurate, but I could wait a moment if there was a narrow cloud belt on the horizon.
I used imagemagick and ffmpeg for image processing. Between the still images, I counted the 50-frame transitions, and this morning’s sunrise, unlike the others, appears as a 45-minute time child summary.
From the series of images, you can see that in the series started a few days after the equinox, the sunrise shifts as much during April as in May and June combined.
