摘要

在这项工作中，我将告诉你我是如何在一个平面的小柱子上推导出E-W线，并将其转移到我的露台的倾斜表面上的。这是在2021年4月25日完成的。这在2021年8月18日再次得到验证。在班加罗尔(北纬约130°)，4月25日和8月18日是零影日(ZSDs)。

MARKING THE MERIDIAN ON A ZERO SHADOW DAY (ZSD)

In this work, I will be telling you how I derived the E-W line on a small pillar with a flat surface and transferred the same on to the sloped surfaced of my terrace. This was done on April 25th, 2021. And this was verified again on August 18th, 2021. In Bengeluru (latitude of Bengaluru is approximately 130° North), April 25th and August 18th are Zero Shadow Days (ZSDs).
