 Unicamp is generally regarded by the Brazilian population as Brazil 's Area 51 , with the government running a secret underground area purportedly called Pavilion 18 , located under the Institute of Chemistry . In 1996 there were reports of an extraterrestrial sighting in the city of Varginha , commonly called the Varginha Incident , followed by additional reports of military intervention in the region and that the extraterrestrial would have been taken to the secret Pavilion 18 area at Unicamp .

 Afternoon is a time when the sun is descending from its daytime peak . During the afternoon , the sun moves from roughly the center of the sky to deep in the west . In late afternoon , sunlight is particularly bright and glaring , because the sun is at a low angle in the sky . The standard working time in most industrialized countries goes from the morning to the late afternoon or evening — archetypally , 9 am to 5 pm — so the latter part of this time takes place in the afternoon . Schools usually let out during the afternoon as well .
