The instant ofgreatest eclipse takes place on 1927 Jun 29 at 06:23:27 TD (06:23:03 UT1). This is 4.9 days after the Moon reaches perigee. During the eclipse, the Sun is in the constellationGemini. Thesynodic month in which the eclipse takes place has aBrown Lunation Number of 56.
The eclipse belongs toSaros 145 and is number 17 of 77 eclipses in the series.All eclipses in this series occur at the Moonsascending node. The Moon moves southward with respect to the node with each succeeding eclipse in the series andgamma decreases.
The total solar eclipse of 1927 Jun 29 is preceded two weeks earlier by a total lunar eclipse on 1927 Jun 15.
These eclipses all take place during a singleeclipse season.
The eclipse predictions are given in bothTerrestrial Dynamical Time (TD) andUniversal Time (UT1).The parameterΔT is used to convert between these two times (i.e.,UT1 = TD - ΔT).ΔT has a value of 24.4 seconds for this eclipse.

At time t1 (decimal hours), each besselian element is evaluated by:
x = x0 + x1*t + x2*t2 + x3*t3 (or x = Σ [xn*tn]; n = 0 to 3)

Predictions for theTotal Solar Eclipse of 1927 Jun 29 were generated using theJPL DE405solar and lunar ephemerides. The lunar coordinates were calculated with respect to the Moon'sCenter of Mass. The predictions are given in bothTerrestrial Dynamical Time (TD) andUniversal Time (UT1).The parameterΔT is used to convert between these two times (i.e.,UT1 = TD - ΔT).ΔT has a value of 24.4 seconds for this eclipse.
