本文探究了通过肉眼观测太阳黑子(NSO)所确定的太阳黑子大小。研究采用了国际太阳黑子数(ISN)、黑子群数以及格林威治太阳照相观测结果(GPR)。根据国际太阳黑子数的相关……(此处“According to the ISN re”表述似乎不完整,推测可能是“According to the ISN record”之类,若有更完整内容,可使翻译更准确)
This article explores the sizes of sunspots as determined by naked-eye sunspot observations (NSOs). The international sunspot number (ISN), the group sunspot number, and the Greenwich photo-heliographic results (GPR) were utilized. According to the ISN results, 64% of NSOs from 1819 to 1918 have been identified as large sunspots. We found that the sunspot sizes had been considerably underestimated using the ISN data (compared to using the GPR data). About 40% of NSOs from 1819 to 1918 have been identified as giant sunspots, which have ranks of sunspot areas smaller than 5%. The results in this article indicate that the majority of NSOs are large sunspots. This calls into question the previous understanding that NSOs include sunspots of all sizes above the visibility limit.
