In case anyone is interested in learning more about this star, Dr. Brad Schaefer wrote a nice article about it in the March 2024 issue of Sky and Telescope (subscription required):
My organization, the AAVSO, has material that can help you learn how to observe variable stars and make scientifically useful measurements. You can do this by eye, with binoculars, with a telescope, or with various digital sensors. In the case of T CrB, visual observations will yield very useful information. Please see https://www.aavso.org/tutorials and https://www.aavso.org/observing-manuals for more information.
