Active Dates: April 17, 1991 – April 17, 1991
Abstract:
Observations and discoveries of Supernova 1991T in NGC 4527, Nova Herculis 1991, and Nova Centauri 1991. Stephen Knight discovered Supernova 1991T visually in NGC 4527. Independent confirmations and recent observations are provided. Observations of Nova Herculis and Nova Centauri are also included.
Justification:
Monitoring the brightness and behavior of Supernova 1991T, Nova Herculis 1991, and Nova Centauri 1991 facilitate understanding their characteristics and underlying physical processes.
