You can see the solar eclipses or the combined eclipse catalog by clicking "Solar Eclipses" or "All Eclipses" in the top-right tabs.

Lunar Eclipses, 1840–1821 BC

Note that eclipse dates are specified relative to UT. You have not selected a timezone for eclipse timings, so all times are shown in UT (essentially GMT).
28 Apr, 1840 BC
max: 22:14 UT
Partial Lunar Eclipse
(umbral mag. 0.09; Saros -8)
A tiny bite out of the Moon may have been visible at maximum, though just 9% of the Moon was shadowed in a partial eclipse which lasted for 1 hour and 8 minutes. A shading across the moon from the Earth's penumbral shadow should have been visible at maximum eclipse. 		   
23 Oct, 1840 BC
max: 18:24 UT
Partial Lunar Eclipse
(umbral mag. 0.56; Saros -3)
The Earth's shadow on the moon was clearly visible in this eclipse, with 56% of the Moon in shadow; the partial eclipse lasted for 2 hours and 44 minutes. 		   
18 Apr, 1839 BC
max: 11:52 UT
Total Lunar Eclipse
(umbral mag. 1.57; Saros 2)
The Moon was plunged into darkness for 1 hour and 34 minutes, in a deep total eclipse which saw the Moon 57% of its diameter inside the Earth's umbral shadow. The visual effect of this depends on the state of the Earth's atmosphere, but the Moon may have been stained a deep red colour. The partial eclipse lasted for 3 hours and 31 minutes in total. 		   
12 Oct, 1839 BC
max: 19:29 UT
Total Lunar Eclipse
(umbral mag. 1.79; Saros 7)

While the visual effect of a total eclipse is variable, the Moon may have been stained a deep orange or red colour at maximum eclipse. This was a great spectacle for everyone who saw it. The partial eclipse lasted for 3 hours and 55 minutes in total. 		   
8 Apr, 1838 BC
