We can conclude that The star is moving toward us; shift to a shorter wavelength.
The transfer of an electron to a higher energy level, such as n = 1 or n = 2, occurs when a hydrogen atom absorbs a photon. The Balmer series refers to this group of hydrogen emission spectra.
The phrase "blueshift" describes how light waves change as an object approaches toward us in space, shifting wavelengths toward the blue end of the spectrum. Change to a shorter wavelength when the star approaches us. A shorter wavelength indicates a blueshift (shift to the blue end of the spectrum), which indicates that the object is travelling in our direction.
Therefore, We can conclude that The star is moving toward us; shift to a shorter wavelength.
