Images of the Palestinian territories were restricted as well despite not being explicitly referred to in the ruling. The limit was dropped in July 2020, however, as of 2024, the entire region remains blurred in Google and Apple satellite imagery. [dubious – discuss] This is the largest area subject to this form of restriction. [10
Sky-Map.org (or WikiSky.org) is a wiki and interactive sky map that covers over half a billion known celestial bodies. [1] WikiSky is designed, in part, as a wiki.Users can edit information about different stars by writing articles, adding Internet links, uploading images, or creating a special interest group for a specific task.
In 2001, Attilla Danko, computer programmer and amateur astronomer, began to summarize Rahill's hundreds of forecast maps by displaying only one pixel, from each map, laid out in rows. [3] The resulting meteogram, called a clear sky chart, showed all of Rahill's forecast data, but for only one location. Danko writes "It shows at a glance when ...

When Globe at Night observations are averaged together, they are very strongly related to the sky brightness in the location. This is a single panel from this image . The standard deviation of an individual Globe at Night observation is approximately 1.2 stellar magnitudes. [ 2 ]
The scanning resulted in images 14,000 x 14,000 (DSS1) or 23,040 x 23,040 pixels (DSS2) in size, [17] or approximately 0.4 (DSS1) and 1.1 gigabytes (DSS2) each. The scanning of First Generation DSS takes a little under seven hours per plate to complete. Due to the large size of the images, they were compressed using an H-transform algorithm.
Cloud cover (also known as cloudiness, cloudage, or cloud amount) refers to the fraction of the sky obscured by clouds on average when observed from a particular location. [2] Okta is the usual unit for measurement of the cloud cover.
