Done berkman :) On-topic : I've tried to solve the problem whole night with no results, I think I'm missing something important. Anyone with experience could give me some heads up ? Not sure where to begin..

Of course there's the basic m1 - m2 = -2.5 log10 ( F1 / F2) Where we can inputed m1 and m2 , though not sure which would I put in first. Like m1=mg and m2=mg+sn. The final question is what was the Supernova's magnitude in the flash. Not sure this formula is useful in that way.

Don't really have any equation or even a far-near one that would help in this problem. There is no actually luminosity mentioned as the numbers only state for apparent magnitude . I searched the whole net for relation between galaxy and supernova apparent magnitude, though did not find anything...

I'm sorry I did a mistake in the text, there's not luminosity mentioned. In a distant galaxy a supernova flash occurred. When supernova reached brightness maximum, galaxy apparent magnitude was 17,6. Before the supernova flash the galaxy apparent magnitude was 18,0. What was the supernova's...

Hello community, I really need help with few assignments! First one would be about Supernova: In a distant galaxy a supernova flash occurred. When supernova reached luminosity maximum, galaxy apparent magnitude was 17,6. Before the supernova flash the galaxy apparent magnitude was 18,0...
