# SkyWeek

SkyWeek was a weekly astronomy television program created by Sky & Telescope magazine. The show was hosted by Tony Flanders, associate editor of Sky & Telescope magazine. Each episode of the program was released in one, three, and five-minute formats; and, the show's content and format were similar to that of another weekly astronomy program called Star Gazers. SkyWeek was carried by many PBS affiliates.

## Content

SkyWeek was an educational program that described celestial events for the upcoming week. The show was aimed primarily at the general public and required no prior knowledge of astronomy. However, it also contained information that was likely to be interesting to experienced amateur astronomers. It depicted celestial objects in the night sky that could be seen without special equipment such as telescopes. Sky and Telescope's associate editor, Tony Flanders hosted the show, which was available in one-, three- and five-minute versions.

## Production

SkyWeek was produced by New Track Media, which publishes Sky & Telescope magazine. The show was distributed to PBS stations through American Public Television.
Images from the Hubble Space Telescope and many other professional and amateur sources were used in the production of the show.
On April 16, 2014, Tony Flanders announced that the episode covering the week of April 28 to May 4, 2014, would be the last for the series. Flanders reported that the series was being discontinued because of insufficient money from sponsors required to cover the show's costs.

## Episodes

Episodes were titled by the week of the events they describe. The production code used was of the form YYMMDD (2 digit year, 2 digit month, 2 digit day) for the date the episode was best suited to be broadcast.

### Season 1: 2011

The show premiered on November 19, 2011, with the inaugural episode covering the week of November 21 to 27, 2011.
