Solar eclipse of 1 May 1185

The solar eclipse of 1 May 1185 was a total solar eclipse observed in the territories of Central America, Northern Europe, Eastern Europe, and Kazakhstan. The eclipse is in the Solar Saros 115 series and is number 30. The eclipse shadow on the Earth's surface was at its greatest at 13:18:02 Universal Time. The sun was in Taurus constellation at this time.

The shadow axis passes between the Earth's center and the north pole, the minimum distance from the center of the Earth to the Moon's shadow cone axis is 3,357 kilometers. The average length of the Moon's shadow is 373,320 kilometers. The distance from the Earth to the Moon on 1 May 1185 is 347,727 kilometers. The apparent diameter of the Moon in 1.0736 times more apparent than the sun. The shadow had a maximum width of 280 kilometers. It began on the west coast of Central America and crossed the Atlantic Ocean in a northeasterly direction. The shadow passed through present-day Nicaragua and the island of Haiti. The maximum duration of the eclipse was in the middle of the North Atlantic at coordinates 46 ° N, 37.2 ° W longitude. The solar eclipse is a long total eclipse that lasted for 5 minutes and 10 seconds. The eclipse magnitude is 1.0736. The eclipse was preceded two weeks earlier by a partial lunar eclipse that happened on April 16.

A partial eclipse came ashore in Scotland, crossed the North Sea and entered territory of Norway. According to astronomer Sheridan Williams there was probably a drop in temperature that happened at the time of the eclipse, which was around 2 pm in Scotland. He says that it was Scotland's fifth longest total eclipse being 4 minutes and 40 seconds there. Williams also notes that it is possible that some adults in Scotland saw two total eclipses in their lifetime, since the previous one was 52 years before.

After passing through present-day Sweden the eclipse touched a part of Finland and covered the northern part of the Baltic Sea at the Gulf of Finland. The eclipse then entered Russia. The eclipse's shadow touched part of what would be St. Petersburg, as well as Novgorod and Rostov. As the eclipse journeyed in a southeasterly direction the shadow passed through locations of current Nizhny Novgorod, Kazan, Ufa and Magnitogorsk. The eclipse shadow started diminishing when it entered in territory of present-day Kazakhstan and extinguished totally after about 30 miles before reaching location of Astana.
