Lunar Eclipse of June, 15, 2011: Three-color umbra surface photometry

TL;DR

This study presents multi-band photometric observations of the June 15, 2011 lunar eclipse, analyzing umbra brightness and atmospheric effects, revealing aerosol pollution impacts on Earth's atmosphere.

Contribution

It provides detailed three-color photometric maps of the lunar umbra during the eclipse and compares observed brightness with atmospheric models, highlighting aerosol pollution effects.

Findings

Photometric maps of the lunar umbra were created.

Radial brightness dependencies match atmospheric models.

Dark umbra anomalies correlate with aerosol pollution.

Abstract

The paper contains the result description of the photometric observations of the Moon surface during the total lunar eclipse of June, 15, 2011 conducted in southern Russia and Ukraine in three narrow spectral bands with effective wavelengths equal to 503, 677, and 867 nm. The photometric maps of umbra are built, the radial dependencies of relative brightness are compared with the theoretical ones for gaseous atmosphere. Dark anomalies of umbra are shown and related with the aerosol air pollution of the definite regions above the surface of Earth.
