Draconis 5.7), and intermittent clouds in east. From 21:05 UT of a cloud in
a southern part of the sky.

Observations meteoric shower Perseid in night with 10 on 11 and with 11 on
August 12 1999.
Geographical longitude 48d05mE
Geographic latitude 54d19mN
In the first night northern and east part of the sky was closed by clouds.
But in west and in the south of clouds was not, Lm in neighbourhoods of a
head Draconis 5.8.
August 11 we observed partial solar eclipse. In our point of observations
its value has made 61 %. Around of a maximum of eclipse the weakening of a
daylight was well noticeably, seemed unnatural. The major impression was
produced by numerous solar reflections of a lightbeam, which were
transparent through foliage and were well appreciable on white table...
Then, unfortunately, conditions of observations considerably have worsened,
the mist (Lm in neighbourhoods of a head Draconis 5.5) and clouds (look the
table of a cloudiness).
