New Observing Section Created to study Young Stellar Objects (YSOs)
Michael Poxon has taken it upon himself to head a new AAVSO section on his favorite class of variable star: Pre-Main Sequence Stars (YSO/PMS). The AAVSO has had a long history of working with such objects, especially the "Orion variables" that were monitored by many visual observers for years.
