In the article titled “Using Sidereal Rotation Period Expressions to Calculate the Sun’s Rotation Period through Observation of Sunspots” [1], there was an error in Table  1, which should be corrected as shown in Table 1.

Table 1 
Part of the observation record of 2013 sunspots (taking 6 days).

Additionally, in “Method III: Calculation of the Solar Rotation Period,” the text reading “for example, the heliolongitude of sunspot number 1642 in 01-03-2013 is 252.16°. After 6 days, heliolongitude = 252.34° (Table  1)” should be corrected as follows.

“For example, the heliolongitude of sunspot number 1642 on 3 January 2013 is 252.16°. After 6 days, heliolongitude = 252.34° (Table 1).”
