Today, the dashed light is clearer than it was yesterday. The bottom dash is slight, but it hits the corner. From tomorrow the width of this light becomes thicker and stronger; the light can be regarded as a dotted line until about the fifth day, the 25th of May.
May 23, the third day of the dashed spotlight.
The observation is impressive today. A dash starts appearing one by one from the top. It takes about three minutes for up to six dashes to appear (see closeup below).
Is the roughness of this triangular stone surface deliberate? It plays perfectly!
The dashed lights move downward. Approximately 3 minutes until the sixth dash appears. The six dashes will eventually disappear, one by one from the bottom. The show time of the dashed line spotlight continued for 30 minutes after it started.
