# Change in absolute magnitude caused by a change in apparent magnitude

Imagine that we have an object with apparent magnitude $$m_1$$, later, we observe that the same object appears with an apparent magnitude $$m_2 = m_1 + \alpha$$, then what we can say about the absolute magnitude M? By the definition I believe we find that the absolute magnitude after the change in apparent magnitude will be $$M_2 = M_1 + \alpha$$. But this make sense? I mean, the absolute magnitude is that, absolute, what are your thoughts in this? What will be the change in the absolute magnitude after a change in the apparent magnitude?

• By magnitude do you mean mass? Secondly, what is meant by absolute?
