Delta T : LUSENET : Astronomical_Calculations : One Thread

Does anyone knows where I can get the lates values of Delta T in the Internet? Thank you.

All I can come up with here is

Bill Gray gives a formula for values of delta_t from J2000.0 onward for a few centuries (no quadratic term).

DeltaT( Year) = 69.3 + 123.5 * dt + 32.5 * dt * dt dt is time from J2000.0 in centuries.

There was a big discussion about this on sci.astro.amateur some time ago - try a Deja search??
