Solution:

<br/><br/>

During the CTF, I solved this challenge in a different way, but after the CTF I solved it in a better way.

I will show you the better way in this writeup...

<br/><br/>

First of all, I used Bing to reverse search that image, and I found a similar image:

<br/><br/> <br/><br/>

<br/><br/> <br/><br/>

<br/><br/>

That article was published in November 2019: <br/><br/> <br/><br/> <br/><br/> <br/><br/>

Now I know that the possible year is 2019, and the possible month is November, and I need to know the exact day of that image...

so I searched for satellite online maps, and I found this great site: (https://zoom.earth/)

<br/><br/> <br/><br/> <br/><br/>

I checked all the days in November 2019 but I didn't find the exact image

So I decided to check september and October, and I found the exact image in 15-09-2019!
