Did I see a supernova explosion? I think I just saw a supernova explode with my own eyes through my GSO 12 inch Dobsonian. Please tell me what it was! I am still trying to find what it was it was mindblowing!
I went out on my roof around 18:20 (New Delhi, India) and was looking up thinking we are going to have clear skies tonight.
Suddenly I could see the bright star without the telescope and I was surprised to see such a bright object near zenith so I ran in and got my telescope out.
When I looked through the scope It was looking like a bright bubble very shiny and the outer surface seemed brighter. I thought my collimation was out so I collimated the scope and it was not too off.
After collimation, I could see a small object in orbit around the star/object. As I continued to observe it, it suddenly exploded like fireworks and tiny particles shining very brightly started to swirl in waves and dimmed quickly. This was around 18:38 I took pictures with my phone through the eyepiece and the sky was still lit and blue in colour.
The below pics are edited in snap seed on my phone.
Supernovae increase in brightness over several days and decrease over months.  Thus, whatever you saw, was not a supernova, sorry.
