Although the IAU created 88 modern constellations, it is not possible to view all 88 from the Pacific Northwest. Some of them are only partially visible, while others are completely visible. As part of the research into all of the constellation, we thought that some of this work would be better shared in interesting snippets like this, rather than the typical format.

It turns out that 68 of the 88 are in some form visible in the Pacific Northwest, and 20 not being visible at all the Pacific Northwest.

Visibility

The following constellations are not visible in the Pacific Northwest at any time of the year, as they are too far to the south:

Antlia, Aro, Pavo, Tucana, Telescopium, Pictor, Circinus, Triangulum Australe, Hydrus, Dorado, Crux, Mensa, Apus, Chamaeleon, Norma, Reticulum, Volans, Octans, and Musca

The following constellations are only partially visible from the Pacific Northwest:

Indus, Grus, Horologium, Vela, Pheonix, Carina, and Corona Australis

The remaining constellations are entirely visible in the Pacific Northwest.
