IC 1283

LBN 47

Set a site to see tonight's sky

When IC 1283 is up, how long it stays usable and when it is in season all depend on where you observe from. Set your site and this page adds tonight's answer and its year.

Set it on Tonight

The science

What you are looking at

In one sentence

Interstellar hydrogen ionised by the ultraviolet light of hot, young stars embedded in it.

Class explainer for H II region (catalogue type).

The facts

IC 1283 is an emission nebula in Sagittarius, catalogued as LBN 47. SIMBAD gives no distance for it, so its true size and light-travel time can't be worked out here. On the sky it spans 15′ — 48% of the full Moon's width.

Sources: AstroBrain catalogue; Lynds B.T. 1965, ApJS 12, 163, via CDS/VizieR VII/9.

For scale

Angular size, as it would sit on your sky.

Sky maths: apparent positions with refraction, one-minute steps; usable = full astronomical dark, at least 30° up and clear of your skyline. Survey images: CDS, Strasbourg (DSS2 and other surveys). Science: SIMBAD. The hours, heights and Moon on this page use no weather forecast; the rank is this target’s place in the Targets list, whose score also counts the cloud forecast when there is one.
