White balance is a matter of taste mostly. Some prefer photos in a certain look (warm or cold). This can be achieved with the white balance. Unless you shoot in RAW and post-process on your desktop or laptop, you want to get the right white balance for you when you are out shooting. Your camera probably has different presets (sun, shadow, etc). Try them out and choose what looks best to you. If you have the option K (temperature Kelvin), use it. Aurora photos come out the best somewhere between 3000…4800K.
