Since its discovery in early 2023, comet Tsuchinshan\u2013ATLAS promised to be one of the great comets of the 21st century. Many astronomy outlets published optimistic articles, predicting a comet potentially as brilliant as Hale-Bopp, which graced us with a spectacular display in 1997.\u00a0<\/p>\n\n\n\n
Most comets that visit us aren\u2019t bright enough to be seen without telescopes or binoculars. On average, it takes five to ten years to enjoy one that is easily visible to the naked eye. The most recent in this category was NEOWISE, which inspired us to step out of our homes during the height of the COVID-19 pandemic in 2020. <\/p>\n\n\n\n
Like many amateur astrophotographers, I began planning months ahead to observe the Tsuchinshan\u2013ATLAS comet. From my location, I expected to see it leading the Sun at dawn towards the end of September 2024; later, from the end of the second week in October, I would see it rising gradually every day after sunset. I selected several observation spots with clear views to both the east and west. I only had to wait.<\/p>\n\n\n\n
In early July, a paper by astronomer Zdenek Sekanina<\/a> announced that the comet was doomed, and it would disintegrate before reaching perihelion (its closest approach to the Sun). For weeks, many outlets echoed Sekanina\u2019s prediction, supporting the pessimism with recent observations indicating that the comet\u2019s brightness wasn\u2019t increasing.<\/p>\n\n\n\n Then, by late August, things started looking promising. The comet\u2019s light curve<\/a> suggested it would behave as initially predicted. This is typical: comets are known for being fickle, and they don\u2019t seem to care what astronomers predict about their brightness. Once again, I had to wait.<\/p>\n\n\n\n
