Danjon Number
and Visual Magnitude Estimates
of the 2022 May 15-16 Total Lunar Eclipse made
by the
Brazilian Lunar Eclipse Watchers
Danjon Estimates |
<L>=2.0±0.5 (Moderately
dark eclipse; orange
southern half with L=2.5 and very dark northern
half with L=1.5) |

(1), Matias Alves (1), Guilherme Rueda (1), Rodolfo
Matos (1) --Total of
24 Danjon Number estimates |
Highlight: Marcos
Jerônimo and his team applied the author`s
“Band Danjonmetry” to estimate L. |
Estimates of Visual Magnitude |
<m>=-0.8±0.3 (Consistent
with <L>, indicating
a moderately dark
eclipse) |
Caio Correia (1), Helio C. Vital (1), Luiz A. Araujo (1),
Niercey Justino (1), Willian Souza (6), Alexandre
Amorim (3) –Total of 13 estimates of the visual magnitude of the Moon |
Photographs |

Highlight: The blue ozone
fringe just
inside the border of the
umbra captured by Eneida Pereira 2 minutes before
