AbstractUnusual short-period comet 29P/Schwassmann-Wachmann 1 inspired many observers to explain its unpredictable outbursts. In this paper large scale structures and features from the inner part of the coma in time periods around outbursts are studied. CCD images were taken at Whipple Observatory, Mt. Hopkins, in 1989 and at Astronomical Observatory, Modra, from 1995 to 1998. Photographic plates of the comet were taken at Harvard College Observatory, Oak Ridge, from 1974 to 1982. The latter were digitized at first to apply the same techniques of image processing for optimizing the visibility of features in the coma during outbursts. Outbursts and coma structures show various shapes.

Extreme ultraviolet observations of the chromospheric network in a coronal hole obtained in 1973 by the Harvard College Observatory experiment aboard Skylab are analyzed. Upper and lower limits to the actual emission measure in UV spicules have been obtained, and the consistency of the derived values with the hypothesis that UV spicules are Hα spicules falling back after being heated is discussed.

The staff of Wolbach Library, in collaboration with partners at both the Smith-sonian Institution and Harvard University, has begun a complex digitization and transcriptioneffort aimed at making a large collection of historical astronomy research more findable, accessible, interoperable, and reusable (FAIR). This collection of material was originally produced from the mid-18th century through the early 20th century by researchers at the Harvard College Observatory and was recently re-discovered in the HCO Plate Stacks holdings. The team of professionals supporting the effort to make this century and a half old science FAIR have developed a novel, distributed workflow to ensure that people can engage critically with this material to the fullest extent possible. The project’s workflow is guided by the collections as data imperative conceptual frameworks and is now being referred to as Project PHaEDRA, or Preserving Harvard’s Early Data and Research in Astronomy.
