Bruno Meurers recently pointed out a misprint which was never affecting any version of Eterna. Nevertheless, it should be noted that in several publications , ,  the mass of the tide-generating body should appear instead of the mass of the Earth in the degree-1 terms of the tidal potential equation. In the thesis … Read More »
IERS informed that the USNO’s public-facing websites will be disconnected from the Web on 24 October 2019.
