Description:
1998-1-1040a-m is a collection 13 sheets of tan cardstock onto which are glued photographs of Harvard College Observatory buildings, scientific instruments, and research stations (including that in Arequipa, Peru), celestial photographs taken with Harvard astrographs, and records of data analysis (much of it done by women "computers" employed at the Observatory). The cards were used to illustrate a talk about the Observatory and its research.
Topics include stellar spectroscopy, photometry, novae, binary stars, and variable stars. The images and graphs are captioned in ink in a cursive hand, perhaps by Williamina Fleming.
This particular card shows:
Spectra of stars in Carina. Photographs of globular clusters. Novae photographs and distribution graphs.
Pencil writing on the reverse of the card:
"Early Work on Novae and other objects. Upper left objective prism plate on eta Carina region"
