morning star, rising as follows: On the 1st at 5:54 a. m.; on the 13th,
on which day also he reaches his greatest western elongation (26° 12′),
at 5:41 a. m., or about 76 minutes before sunrise, and on the 29th at
5:49 a. m. On the 26th, at 7:00 a. m., he is farthest from the sun. His
diameter diminishes from 8.4″ on the 1st to 5.6″ on the 29th.
