ALMA | ... In this section, we explain why we need to correct phase fluctuations and ALMA's strategy to do this. Rapid fluctuations will be corrected with water vapour radiometers (WVRs). The Cavendish Astrophysics Group was also a leading contributor to the ALMA prototype WVRs, which were put through their paces in tests at the Submillimeter Array (SMA). ... The Cavendish Astrophysics Group in partnership with the Onsala Space Observatory built two prototype WVRs for the ALMA project. ...

... Phases of the Moon is at the top of the list of things that students seriously misunderstand. ... This phase is called "new moon" (like "no moon"). ... Note: although the Moon is closer to the Sun during new and crescent phases, it is still 400 times closer to Earth; i.e., the Sun is VERY far away in reality.) ... When the Moon reaches the position directly opposite the Sun, as viewed from Earth, the half viewed from Earth is fully illuminated (unless the student's head is causing a lunar eclipse). ...

... The growth phase starts the substorm process. ... Furthermore, a thin current sheet (TCS, down to 0.1 Re) forms just tailward of the dipole-like field lines (6-15 Re). This can be important for the triggering of the substorm (onset of the expansion phase). ... Res. ... Kaufmann, R. L., Substorm currents: growth phase and onset, J. Geophys. ... Kirkwood, S., and L.
