February 26 after Sunset
A crescent moon will travel beside the brilliant off-white planet Jupiter. Below them is the brilliant white planet Venus. Jupiter and Venus will appear very close March 12 & 13.

As the sky darkens through binoculars as many as four of Jupiter's largest moons can be seen.

The Anomalous Transport Rocket Experiment (ATREX) will study the 200-300mph ultra-high level jet stream at the edge of space 60-65 miles above the Earth's surface. For details on the mission see
NASA - NASA Jet Stream Study Will Light up The Night Sky.


Crescent & Planets PhotoOps
(and beautiful binocular & naked eye views too.)

March 24-27 after Sunset
There will be good photo opportunities with the crescent moon in the western sky. (See the series of images just below.) Total darkness comes about 1½ hours after sunset. Between half an hour to an hour after sunset are some nice twilight skies. You can step outside any evening starting now, see the brilliant planets Jupiter and Venus, get an idea of lighting at various times and take some test shots.

After dark the two star clusters closest to Earth are easily seen above Jupiter and Venus. To the naked eye the Pleiades cluster appears as a tiny white dipper shaped pattern of stars standing above brilliant white Venus. The Hyades cluster appears farther above as a larger V-shaped pattern of stars with the bright and orangeish star Aldeberan at one corner. Binocular views of these star clusters are spectacular.

On the east side of the Sea of Cortez (Gulf of California) is a circular area of low clouds rotating counterclockwise. High clouds above it are moving clockwise. Deep convection is bursting near the center.UPDATE: A satellite loop of the system described is in comment 1. Similar systems continue to appear. Below I've added self updating satellite images and surface maps of the area.I'll add loops of similar systems that I see to the comments. Currently there are...
