“…The duration of the totality was exceptionally long and it was the first solar eclipse where spectroscopic observations were made, leading to the discovery of helium (Nath, 2013). It was observed at several locations on the Earth, from Aden in the west to Indonesia in the east, by Austrian (Aden), English (India), German (Aden and India), French (India and Siam), and Dutch (Indonesia) astronomers (see Launay, 2012;Mumpuni et al, 2017;. One of the French contingents of astronomers observed the eclipse from Wah-koa in Siam (under the black spot in Figure 9) in the presence of King Rama IV (Mongkut) of Siam .…”

Many of the calendrical records in Southeast Asia contain information on the longitudes of the Sun, the Moon and the planets-something that is valuable for the dating of these records. Both the Burmese and the Thai use calculation schemes for the longitudes of the Sun, the Moon, and the planets that are almost identical to the original Sūryasiddhānta schemes. After the change to the Thandeikta calendar the Burmese changed some of the parameters involved, in general following those of the modern Sūryasiddhānta.
