I am back. I spent a week in Bolivia near Lake Titicaca, the largest lake in South America. It went well. There were 8 of us in the group, and we were out every night observing the stars and constellations of the southern hemisphere. Skies were clear. My roommate located 45 galaxies in a single night. We made day trips to Tiwanaku, a pre-Columbian archaeological site, and to La Paz, the highest capital city in the world. The lake and the Andes were beautiful. They fed us well at the hotel, and I ate llama.
The astronomy was good, and I learned. Alpha Centauri and Beta Centauri are called the southern pointers because they point to Crux. Crux points to the south star, Sigma Octantis. It is curious that Bcrux has a proper name (Mimosa) and Acrux does not. Northern constellations appear upside-down in the south.
Alpha and Beta Centauri were "the eyes of the llama" to pre-Columbians.
Alpha Centauri is a triple star. Smallish Proxima Centauri is actually the closest star.
