Solar eclipses and elongation
I wrote a PC program to simulate solar and lunar eclipses.
When I need to find the next solar eclipse, I use the elongation of the Moon. Does anybody know the maximum elongation at which a solar ecplipse could be seen? Thanks Cristiano |

Does anybody know the maximum elongation at which a solar ecplipse could be seen? Assuming that elongation is measured from the geocentric, and that the Earth and Moon are both near perihelion and perigee respectively, and further assuming that the observer is where the tangent line joining the limbs of the Earth and sun kisses the Earth, then I calculate about 2.00 degrees for the elongation. Of course, this does not take into account any atmospheric effects like diffraction. |

Sorry, make that about 1.55 degrees. Of course, this does not take into account any atmospheric effects like diffraction. |
