The two coverings of Mars by the Moon occurred 26.5 days apart. What (roughly) was the moon phase during these coverings?

The interval between the coverings in the condition of the problem is less than the stellar orbital period of the Moon (27.3 days). Consequently, Mars at this time moved in the sky relative to the stars towards the Moon, from east to west. This could only be near the opposition of Mars, therefore, the phase of the moon was close to full.
