Named in honor of Edwin L. Aguirre and Imelda B. Joson, who have popularized astronomy in the Philippines for more than 15 years. Their 1985 book about Comet Halley, The Second Coming, is the first and only astronomical book ever written by Filipino authors. They designed two astronomical stamps issued by the Philippine Postal Service, and in 1990 the Philippine Department of Science and Technology commissioned them to construct a 0.44-m reflector, the largest operational telescope in the country, for a public observatory in Manila. That same year, the couple obtained the approval of then-president Corazon Aquino for an executive proclamation declaring an annual National Astronomy Week. (M 25978) _ _.
