Clipping of heliotrope.

Noun

helio (plural helios)

1. A heliotrope (surveying instrument).
   • 1874, Verplanck Colvin, Annual Report on the Progress of the Topographical Survey of the Adirondack Wilderness of New York, for the year 1873:

     A helio or sun-reflecting signal was evidently the desideratum.

   • 1925, U.S. Coast, Geodetic Survey, Special Publication - Coast and Geodetic Survey, page 62:

     A light keeper's duties require him to be alone on a station for days or even weeks at a time, showing a helio to the observer in the afternoon for two or three hours and watching by the signal lamp at night.

   • 1968, Arthur Laidlaw Allan, J. R. Hollwey, J. H. B. Maynes, Practical Field Surveying and Computations, page 258:

     On a cloudy but bright day, it is possible to use a helio effectively over moderate distances of about 6 miles. Light keepers should be made aware of this, since they often think that brilliant sun is essential.
