| Zusammenfassung |
| The present paper considers historical aspects of the earliest known
observations of noctilucent clouds (NLCs). The 1884 and 1885 are discussed
by considering important historical citations by the pioneers of the
earliest known observations of noctilucent clouds. For the first time in NLC
studies, we consider seven major volcanic eruptions: Laki in 1783, Mount St. Helens
in 1800, Tambora in 1815, Galunggung in 1822, Cosigüina in 1835,
Shiveluch in 1854 and Askja in 1875. These all preceded the catastrophic
1883 eruption of Krakatoa, which despite having a lesser magnitude than
Tambora in 1815, had pronounced effects on the atmosphere. These eruptions
represent possible triggers for the appearance of NLCs. For the first time,
we publish an unknown, in English-speaking literature, historical fact on
the first determinations of the altitude of noctilucent clouds made by two
Russian astronomers V. K. Tseraskii and A. A. Belopolskii on 26 June 1885, who
managed to infer the altitude of the clouds in the range of 73–83 km, that
is, for the first time, demonstrating the possible existence of the clouds
at great altitudes in the Earth's atmosphere. Moreover, V. K. Tseraskii was
the first observer to photograph noctilucent clouds in 1885 or 1886, which
is 1–2 yr before the German astronomer O. Jesse, who owns the first
published images of noctilucent clouds. The photographs made by V. K. Tseraskii,
unfortunately, did not reach us. |
