Description2023-07-22 - Cirrocumulus lacunosus - solitary cloud - zenith - DSG1929-11 - crop mid right.jpg	English: A solitary Cirrocumulus lacunosus cloud nearing zenith (at top of image) is almost completely riddled with the namesake "hollows", typically arranged in a net or honeycomb pattern. This image, a crop of the full image, is aligned due west, the cloud overhead moving eastward. Image taken on 2023-07-22, 08:52 from the Aplerbecker Mark, Aplerbeck, Dortmund, Germany. This cloud formation is rather rare and is attributed to a cool layer of the atmosphere interacting with a warmer overlying layer. Deutsch: Eine einzelne Cirrocumulus lacunosus Wolke befindet sich nahe dem Zenit. Sie ist vollständig von den namensgebenden Vertiefungen durchsetzt, häufig, wie hier, netz- oder honigwabenartig ausgerichtet. Diese Aufnahme, ein Ausschnitt der ganzen Wolke, zeigt nach Westen, die Wolke bewegt sich sich nach Osten. Die Aufnahme erfolgte am 2023-07-22, 08:52 Uhr aus der Aplerbecker Mark, Aplerbeck, Dortmund. Diese Wolkenformation ist recht selten und deren Entstehung wird der Interaktion auf der Trennfläche zwischen einer kühleren Wolkenschicht und einer überlagernden wärmeren zugeschrieben.

en: A solitary Cirrocumulus lacunosus cloud.

• This cloud is almost completely riddled with the namesake "hollows", arranged in a typical honeycomb pattern.
• This image is a crop of the full image, aligned due west, the cloud overhead moving eastward through the zenith.
• This cloud formation is rather rare and is attributed to a cool layer of the atmosphere interacting with a warmer overlying layer.
• Taken on 2023-07-22, 08:52 from the Aplerbecker Mark, Aplerbeck, Dortmund, Germany
• This image is part of a sequence taken over a span of 4 min.

See below for technical details concerning the "making of" this image.

de: Eine einzelne Cirrocumulus lacunosus Wolke.

• Diese Wolke ist vollständig von den namensgebenden Vertiefungen durchsetzt, die häufig, wie hier, honigwabenartig ausgerichtet sind.
• Die Aufnahme ist ein Ausschnitt des ganzen Bildes und zeigt nach Westen, die Wolke bewegt sich sich über den Zenit nach Osten.
• Diese Wolkenformation ist recht selten. Deren Entstehung wird auf die Interaktion auf der Trennfläche zwischen einer kühleren Wolkenschicht und einer überlagernden wärmeren zurück geführt.
• Aufgenommen am 2023-07-22, 08:52 Uhr aus der Aplerbecker Mark, Aplerbeck, Dortmund.
• Dieses Bild gehört zu einer Serie, die über einen Zeitraum von ca. 4 min. aufgenommen wurde.

Technische Daten zum Bild: siehe nachfolgende Beschreibung im englischer Sprache.

• Extended colour rendering: This is a true ProPhoto RGB colour space image. All editing has proceeded on a 16-bit basis, based on the original 14-bit RAW file. The JPEG file format definition does allow a 16-bit colour space, but only the 8-bit variant has ever been realised in available image rendering software. Thus this image must be saved as an 8-bit JPG file, nevertheless retaining the ProPhoto RGB colour space.
  If, as opposed to most modern equipment, either your computer or your screen's colour rendering hard-/software does not support 8-bit ProPhoto RGB JPEGs (i.e. supports only JPEGs based on the sRGB colour space), this image may appear somewhat dull both in colour and tone spectrum.
