Star Calendar – October 2007

Star Calendar

October 2007

Star Calendar Planets:

Mercury will sneak past the near side of the Sun (inferior conjunction) on Oct 23, then rush to the eastern morning sky in the end of the month. On November 7 it will appear to the left of Spica, just below and to the left of the waning crescent moon.

Venus shines brightly at about the same height at a given time each morning all month. Watch Regulus and Saturn rise higher and higher each day. On October 7th the waning Moon will join them. Venus waxes gibbous by the end of the month, but becomes more distant too.

Mars makes its longest path across our sky on October 1st and is highest at 5:15AM. Look above Betelgeuse of Orion. Mars is now closer to us than is the sun and it brightens as it draws ever closer and slows its movement against the stars. Watch for the Orionid meteors radiating from the vicinity on or about the 21st .

Jupiter remains in Ophiucus and accelerates its direct motion as it begins to fade. By month’s end it will be noticeably lower in the evening sky.

Saturn appears relatively dim in the eastern morning sky and will create an interesting series of triangles with Venus and Regulus all month. Continue reading

Star Calendar — September 2007

Star Calendar

September 2007

Star Calendar Planets:

Mercury will make a poor appearance in the western evening sky in mid-September. It will dash to the eastern morning sky by late October.

Venus will quickly rise into the eastern pre-dawn sky in September and will shine beside Regulus and Saturn by early October. On October 7th the waning Moon will join them.

Mars rises in the middle of the night in the horns of Taurus as September opens. It rises earlier in the evening and brightens as the weeks pass. Mars makes its highest and longest path across our sky on October 1st when it is of Betelgeuse of Orion – best seen in the south at about 6:00 AM.

Jupiter lingers in Ophiucus above Antares and is in the south at sunset as September begins. It slowly accelerates its direct motion and fades eastward toward the setting Sun.

Saturn appears close to Regulus in the eastern morning sky in mid-September. It may be visible under the waning Moon on September 9th and will have a sojourn with Venus a month later.
