Meteor wind data from the first year of operation of the Falkland Islands SuperDARN radar (52 S, 59 W) are used to characterize the atmospheric tides and background winds in the upper mesosphere above the South Atlantic. Strong (>40 m s−1) semidiurnal tides are observed in the winter time and large amplitude (>60 m s−1) bursts of quasi two-day wave activity are seen in January 2011. Data are in...

We discuss the problem of how to calculate the distance between two cosmological objects given their redshifts and angular separation on the sky. Although of a fundamental nature, this problem and its solution seem to lack a detailed description in the literature. We present a new variant of its solution and quantitatively assess the most commonly used approximation.
