Dipole model of the Earth's magnetic field (MLAT), or geomagnetic latitude, formula_10 is measured northwards from the equator (analogous to geographic latitude) and is related to formula_9 by formula_12. In this case, the radial and azimuthal components of the magnetic field (the latter still in the formula_9 direction, measured from the axis of the north pole) are given by formula_14 formula_15 formula_16 where formula_17 in this case has units of Earth radii (formula_18). Invariant latitude is a parameter that describes where a particular magnetic field line touches the surface of the Earth. It is given by formula_19 or formula_20 where formula_21 is the invariant latitude and formula_22
What The… What The… What The… is the seventh and final studio album by American hardcore punk band Black Flag. The album was originally announced to be released on November 5, 2013. However, on November 5, "What The…" was only released through online streaming sources such as Spotify and Rdio, and a physical release date was pushed back to December 3, 2013. It is the band's first full-length studio album since "In My Head" (1985), marking the longest gap between two studio albums in their career, as well as being their first recording with vocalist Ron Reyes since "Jealous Again" (1980) and
