Mars continues to brighten and appear larger; in Cancer, it shines with minus zero magnitude, 11 arc-seconds, 30° highest at 4:32 AM and sets at 11:54 AM.

Vesta and Ceres are Roman versions of Greek goddesses. Vesta is the goddess of the hearth. Roman homes had hearths for cooking and heat; in fact, the hearth was her shrine. Romans said daily prayers to her in thanksgiving for food and heat. The household fire must never go out. Should the fire be extinguished, a new fire could only be started from another holy hearth or Vesta’s temple fire. At the temple, six Vestal Virgins (unmarried women) tended to the sacred fire day and night. They enjoyed great esteem and were granted important privileges. Vestalia was a religious festival when the Vestal Virgins would clean the temple and relight the flame with a magnifying glass. Special cakes were baked and offered to Vesta.
