Условие

A star is observed from the Earth. It is found that its magnitude is $m_1 = 2^{\mathrm{m}}.74$ when observed at Zenith and $m_2 = 2^{\mathrm{m}}.85$ when observed at $45^{\circ}$ above the horizon. What would the apparent magnitude $m_0$ of the star be if observed from above the atmosphere (from a satellite, for example)?
