In this reply, the aim of the authors is to correct the calculation errors on solar depression angle and azimuth angle as recognized by Dr. Dalin in his critical review. However, these updated and corrected calculations do not affect the possibility for Antonio Colla of having observed the Noctilucent Cloud (NLC) plausible both in the direction and for the duration he described in his observations. In this reply, the authors offer two different interpretations in this regard.

回复'对论文的评论：最早的可数据夜光云观测（帕尔马，意大利公元 1840 年）'

在此答复中，作者的目的是纠正大林博士在其批判性评论中认识到的太阳俯角和方位角的计算错误。然而，这些更新和更正的计算不会影响安东尼奥·科拉在他的观察中描述的方向和持续时间上观察到夜光云 (NLC) 的可能性。在本次答复中，作者对此提出了两种不同的解释。
