How long should stargazers allow their eyes to adjust to complete darkness before counting meteors during the Geminid peak?

Answer

20 to 30 minutes

Achieving maximum light sensitivity in dark conditions is critical for seeing fainter meteors, especially when trying to establish accurate counts or appreciate subtle activity. This process requires the pupils to fully dilate, which is not instantaneous. Observers must commit to remaining in complete darkness, devoid of artificial light sources like white-light flashlights or phone screens, for a duration spanning 20 to 30 minutes to ensure their night vision is fully developed.
