Simultaneous occurrence of solar eclipse and transit of Venus
15232 Apr 05
Transit of Venus and Total Solar Eclipse as seen from location of Greatest Eclipse
16° S from the Equator
The next time an eclipse of the Sun is predicted to occur during a transit of Venus is on April 5, 15232. This is second of only three such simultaneous events during the one hundred thousand years interval 50 000 BC - 50 000 AD. Below are listed specific moments of both phenomena occurring on April 5, 15232. Due to the slowing down of Earth's rotation calendar time of events will be about an week earlier when converted to Gregorian calendar, i.e. end of March 15232. Irregularity in slowing down of Earth's rotation, a.k.a uncertainty in ΔT, however accumulates to a level that it could not be determined where (in terms of geographical longitude only) events will be observable. The only certain thing is path of central solar eclipse will sweep in southern hemisphere. More about the eclipse could be found below.

Hybrid Solar Eclipse
On 5th of April 15232 an oddball type of eclipse will occur. Under rare circumstances, a total eclipse can change to an annular eclipse or vice versa as you follow the eclipse path across Earth's surface. This happens if the curvature of Earth brings different points of the path into the umbral (total) and antumbral (annular) shadows, respectively. Hybrid eclipses are sometimes called annular/total eclipses. On average only one in twenty one eclipses is hybrid. The last hybrid eclipse was in 2005 and the next one is in 2013.
Moons penumbral shadow reaches Earth around 15:12 TT. The central eclipse track begins at 16:15 TT as a 17 kilometre wide annular path. However, the path quickly narrows to 0 kilometres within the first 3 minutes of its trajectory. Continuing along its north course, the path is now total as it rapidly expands in width.
At greatest eclipse (17:53:24 TT), the duration of totality is 37 seconds and the path width is 47 kilometres. As the shadow proceeds along its trajectory approaching the equator, the path begins to narrow as the length of totality decreases. The path becomes annular again around 19:30 UT. A minute later central eclipse ends. Partial eclipse could be observer until Moon's penumbral shadow leaves Earth's surface at 20:34 TT.

Notes
1 This value would be the true value if difference between UT and TT is integer number of sidereal days (86,164.09s). For every 4 seconds of deltaT the location is displaced eastwards by a little more than 1'. However by the year of eclipse difference between UT and TT will be several days, equaling thousands of degrees displacement, and worst of all - uncertainty of the actual displacement is hundreds of degrees, practically giving us no idea in which area eclipse will take place.
