The haze and thin clouds, in which the small halo at 22 degrees around
the sun fully formed, disappeared almost completly when it got dark.
Some aircraft stripes however made some obs impossible.
At 21:30 again thin clouds moved in.

Seems to accelerate slowly

Looks like it is accelerating, but the pattern is complicated. I timed:
11.18 11.59 12.46 12.24 12.07 12.63 14.37 11.30 12.30 12.91

95- 72 C 99-05-02 20:22      LB                       S, mag 4

Period is a combination of two periods. Timings were: 6.94 7.52 6.63 7.66
6.54 7.75 6.95 7.44 6.51 8.18 6.26 7.79 6.68 7.75 6.47 7.82.
This gives 6.62 and 7.74; together 14.36
