There are a scant number of evenings left to see Neptune before it ducks down into bright sunset--and only if your western horizon is clear.

Below are the altitudes at which Neptune can be found in the Baton Rouge evening after twilight is completed...
18 January = 21˚
20 January = 20˚
22 January = 18˚
24 January = 16˚
Twilight ends during this date span anywhere from 6:54pm to 6:58pm CST.

Neptune reaches opposition at midnight this coming nighttime period. It can be found, however, at 10pm tonight; it is 1˚07' east of the magnitude 3.7, K-class variable Lambda Aquarii. Neptune's bluish disk is about 2.4" across at this time.

Tomorrow night's conjunction of Neptune with the Moon may be of assistance for those trying to find this planet, which can be elusive. To the west-northwest of the Moon (about 2˚51') is aforementioned K-class, magnitude 3.7 Lambda Aquarii. Centering onto that star with at least a four- or five-degree field of view will show, 0˚35' to its south, the planet Neptune. Neptune has a color that will distinguish it from any star. The planet should be about magnitude 7.9 right now.
