Since the Aurora is dependent on solar activity, a full moon has no effect on the intensity or color of the Northern Lights. The only potential issue that might arise is from light pollution.
Does full moon affect seeing northern lights?
Contrary to what you may have read or heard elsewhere, the Aurora Hunter's worst enemy is not a full moon. In fact, most Aurora hunters, guides and photographers rather like having a full moon in the sky because it is in itself a thing of great, great beauty and only really impacts negatively on weak Auroral displays.
Is 2021 a good year to see Northern Lights?
"The outlook is favorable as we go forward," Steenburgh said of 2021. Solar forecasters are seeing upticks in active regions as well as in the coronal mass ejections of charged particles that are key to lighting up the northern lights.
