Yerachmiel Ungar asked:
Does Techilas Schkiay (what we call sunset) mean when the total view of the sun has sunken below the horizon and does Netz Hachama (what we call sunrise mean) mean when the total view of the sun is above the horizon?
The Kollel replies:
Yes, Sheki'ah means when the total view of the sun has set below the horizon.
Ha'Neitz refers to when the beginning of the shining of the orb of the sun appears.
