Moon Rides with Jupiter (& Jupiter's Moons)

WunderPhoto: Jupiter, Venus and the crescent moon....Day 2 by rds817 — Sunday February 26, 2012

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.

Annular Solar Eclipse

May 20
Partial begins: 2056 GMT
Annular begins: 2206 GMT
May 21
Annular ending: 0139 GMT
Partial ending: 0249 GMT

A VERY IMPORTANT NOTE ABOUT VIEWING THE ECLIPSE:
"....no matter what, do not use "filters" such as smoked glass, stacked sunglasses, polarized filters, camera filters, candy wrappers, or compact discs. They might reduce the Sun's glare, but enough harmful radiation can sneak through to damage your eyes. Only use materials specifically manufactured for safe solar viewing, or #14 arcwelders glass."

That quote is from Safely View the Upcoming Eclipse and Transit - Observing Highlights - SkyandTelescope.com which gives directions for additional viewing methods such as projecting an image, etc.


Map credit: Eclipse Predictions by Fred Espenak, NASA's GSFC
For a explanation of all the lines and terms on the map see
NASA - Key to Solar Eclipse Maps.

See a zoomable and clickable NASA - Annular Solar Eclipse Map that will show specific times and amount of Sun eclipsed for any locations you select.

Some phase of the eclipse will be visible for most of North America before or during sunset. The path of annularity (where the Sun will appear as a "ring of fire" arround the Moon) is at least 150 miles wide. The path of annularity makes landfall at the California-Oregon border and continues into NW Texas. See the general visibility map for North America.

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...
