Shallow sky

The shallow sky is space within the Solar System, plus the Earth's atmosphere.

Sky phenomena such as planetary conjunctions, solar eclipses, lunar eclipses, as well as atmospheric phenomena like haloes, rainbows, and noctilucent clouds, are all occurring in the shallow sky.

The Shallow Sky Bulletin (ISSN 0897-2532) was published by Stephen M. Smith from 1986 through 2000.

The common practice for publishing comet tables was to display positions at 10-day intervals.

During the 14-year run of SSB, CRAS subscribers were informed about all observable comets.
