Atmospheric optics wavelengths. A halo (ἅλως; also known as a nimbus, icebow or gloriole) is an optical phenomenon produced by the interaction of light from the sun or moon with ice crystals in the atmosphere, resulting in colored or white arcs, rings or spots in the sky. Many halos are positioned near the sun or moon, but others are elsewhere and even in the opposite part of the sky. They can also form around artificial lights in very cold weather when ice crystals called diamond dust are floating in the nearby air. There are many types of ice halos. They are produced
Schempp-Hirth Mini-Nimbus Schempp-Hirth Mini-Nimbus The Schempp-Hirth Mini Nimbus is a 15 Metre-class glider designed and built by Schempp-Hirth GmbH in the late 1970s. In designing the Mini-Nimbus, Klaus Holighaus incorporated the flapped wings from the Glasflügel 303 Mosquito, with the fuselage of the Standard Cirrus. The wings feature trailing edge terminal speed dive brakes-variable camber flaps that limit the vertical dive speed to a maximum of 70 knots when the dive brakes are fully deployed. The name "Mini Nimbus" was adopted to distinguish it from longer-wingspan Nimbus models. It first flew on 18 September 1976. The Mini Nimbus range all feature self-connecting
