Status: SAFED

Abstract: Labels without digital data, documenting the existence of drawings of comet 21P/Giacobini-Zinner made by members of the IHW Amateur Observers Network as part of a rehearsal for the Comet Halley passage. The data referenced were never digitized, but observing parameters are recorded in the null-data headers.
