Edwin Aguirre
Edwin Aguirre joined Sky Publishing in January 1995. As an Associate Editor of Sky & Telescope, he edits the magazine's Astronomy Scene; Star Trails; Northern Hemisphere Sky; Sun, Moon, and Planets; Targets, and Observer's Log departments, including Community News and Amateur Events. He also occasionally writes and edits News Notes and feature articles.

Before coming to Sky & Telescope, Edwin served as president of the Philippine Astronomical Society (PAS) from 1989 to 1991. For many years he and his wife, Imelda B. Joson, were freelance science writers to major daily newspapers in Manila. In 1985 the couple authored a 335-page reference book on Halley's Comet, which was published by the National Research Council of the Philippines. For their book and observations of Halley, they were given the 1986 Padre Faura Astronomy Award by the PAS as well as resolutions of commendation by the California State Assembly in Sacramento.

In the early 1990s Edwin and Imelda conducted research on high-vacuum, thin-film metal coating of telescope mirrors at the Jesuit-run Manila Observatory. There they aluminized mirrors ranging in size from 6 to 12 inches, including the observatory's spectroheliograph. They also designed and constructed two 17.5-inch f/4.5 Newtonian reflectors — for a private observatory in Queensland, Australia, and for the Philippine Department of Science and Technology (DOST).

To date, they have organized and/or led eight successful solar-eclipse expeditions: to the total eclipses in Java, Indonesia (1983); Mindanao, Philippines (1988); Baja California Sur, Mexico (1991); Caribbean Sea (1998); Harput, Turkey (1999); Lusaka, Zambia (2001); and Salloum, Egypt (2006); and to the annular eclipse in New Mexico, USA (1994).

Edwin and Imelda proposed and designed two astronomical stamps issued by the Philippine Postal Service — in 1986 to commemorate Halley's Comet and in 1988 to mark that year's total solar eclipse. For the latter event they also served as technical consultants to the Solar Eclipse National Committee of the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA).

In 1990 they obtained from then-president Corazon C. Aquino an executive proclamation declaring the country's first National Astronomy Week. The event has been celebrated annually ever since.

In 1995 the International Astronomical Union named asteroid 6282 Edwelda in their honor. In 1998, on the occasion of the Philippines' centennial celebration, the DOST and PAGASA gave them the first Casimiro del Rosario Astronomy Award for "exemplary achievements in the science of Astronomy."

Edwin and Imelda live in the suburbs of Boston with their cocker spaniel Bernie and cat Ming. When the weather and their work schedule permit, the couple can be found observing with their 10-inch Meade LX200 telescope at their backyard observatory.
