Chicago, Illinois:  Sunrise, 7:17 a.m. CST; Sunset, 4:42 p.m. CST.  Check local sources for sunrise and sunset times for your location.

Even two months before it passes on the far side of the sun (superior conjunction), Venus is becoming more difficult to see in the morning sky.  It slips into bright morning twilight.

Venus rises 21 minutes later than it did at the beginning of the new year.  This morning it rises 67 minutes before sunrise. By month’s end it rises only 36 minutes before sun rises.

The result is that Venus appears low in a brighter sky.  This morning, it is only about 5° in altitude at 30 minutes before the sun appears.

Because it is brilliant, the planet is visible to the unaided eye, but it is likely behind a neighboring building, tree, or other obstruction.  At this altitude above the horizon, it could be covered by clouds that extend into the distance.

Detailed Note: Thirty minutes before sunrise, locate Venus about 5° up in the southeast.
