Solar eclipse of September 16, 1792

An annular solar eclipse occurred on September 16, 1792. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide.

Description
The eclipse was visible in a small part of Northeast Brazil including Recife, almost the whole of Africa with the exception of the southernmost area, southern Europe, and parts of Asia with much of the west of the Middle East, South India, Southeast Asia and less than half of its southeast islands as well as parts of the Atlantic, the Indian Ocean and the coast of New Holland, Australia. It was part of solar saros 131.

The umbral portion was 93 km (58 mi) long and started over 30–40 miles (40–50 km) east of the island of Boa Vista, Cape Verde, it included northernmost Senegal with Sant-Louis, much of southern Agaouedj (now part of Mauritania), Mali (which had separate principalities at the time), such as Timbuktu and Gao, modern-day Niger, Wadai (now part of Chad), Darfur, areas that are now the South Sudan and Abyssinia what now comprises Ethiopia and Kenya and Somalia (then as Somaliland). The greatest occurred just over 2.5 miles (4 km) east of Lagbogol in present-day Wajir, Kenya at 1.3 N, 39.9 W at 9:13 UTC (12:13 local time) and lasted for over 3 minutes.

The eclipse showed up to 50% obscuration in Morocco including Marrakesh, Ottoman Algiers (now Algeria), Libya, Egypt and Yemen, Nubia, near the tip of the Horn of Africa and the Chagos Archipelago, and on the other side west of Cape Verde, near the island of São Tomé, the Congo including Katanga, Malawi, modern day Mozambique and southcentral Madagascar.
