Southern SARV's from South Africa R.W. Jones and his colleague Fanie de Villiers continue to accumulate interesting new results on southern small-amplitude red variables. The comparison stars are the same as for HR7045. The purpose of HOA is to support science and math education in the schools and colleges, by developing and integrating science, math, and computer skills.
Students experience the excitement of doing real science with real data.
We hope that some of them will take up variable star observing as a serious interest, and swell the ranks of our visual observers. HOA is also an excellent way for amateur astronomers of all ages to learn about variable stars and other aspects of astronomy.
