Our current sunspot maximum in the 11-year cycle is supposed to occur next year. We also have two significant solar events occurring over the next two months. On May 20, 2012 there will be an annular eclipse of the Sun the path of which crosses into the western US. Albuquerque, NM is directly in the path of maximum coverage which will occur shortly before sunset there. In an annular eclipse the Moon is far enough away in its orbit about the Earth that its silhouette won’t cover the entire face of the Sun. The second major event is the transit of the planet, Venus, across the face of the Sun. This will occur on June 5, 2012. Locally, if you have a clear view of the western horizon, the transit will begin about 3 hours before sunset and the Sun will set with Venus about 50% of the way across the face of the Sun. For those more adventurous people (and slightly more wealthy), you can see the complete transit from the summit of Haleakala volcano on the island of Maui in Hawaii.
In addition two great MUST SEE solar events are coming up soon. A partial Solar Eclipse on Sunday afternoon May 20, 2012 and the much anticipated transit of the planet Venus in front of the Sun on Tuesday June 5, 2012. And the BIG ONE – A TOTAL SOLAR ECLIPSE – Aug 21, 2017 across NE Kansas and the central Nebraska !!!
The Transit of Venus is coming up Tuesday June 5, 2012. Here in Midwest it starts about 5:04 PM and is still in progress at sunset. Sunset in Tulsa is 8:35 PM but will be later in OKC
It will require solar filters and at least filtered binoculars to observe
Since Venus is only 58”wide - the very limit of angular visibility without magnification.
Here is a link to several valuable information resources from the Astronomical Society of the Pacific.
Including a 2 page card resource, 8 page historical review, Universe in the Classroom with teacher activities.

Superflares from Sun-like Stars— May 16, 2012
NASA's Kepler mission is finding solar-type stars that emit jaw-dropping explosions of high-energy particles and radiation. Now astronomers are looking into why some solar-type stars emit superflares — and why the Sun never will.
Europe's New Eye on the Sun— May 15, 2012
The just-completed Gregor telescope, situated on Tenerife in the Canary Islands, ranks as Europe's largest solar sentinel and the third largest in the world.
Millennial Calendar Found in Mayan Ruins— May 14, 2012
Never mind what the doomsayers tell you: Remarkable paintings in a room amid Guatemalan ruins prove that the ancient Maya knew more about celestial cycles than we thought — and that they didn't predict the world's end in December 2012.
Now is your chance to participate in an International effort to survey the effects of light pollution on our night skies. The project is to observe and count the number of stars you can see in the constellation of Orion then pinpoint your location on the world map and enter your results on the world wide web.
A great weekly online video of things you can see with the naked eye. These 5 minute video segments feature events that anyone can enjoy by merely going outside and “Looking Up”! Keep this one on your favorites list - http://www.stargazersonline.org/
Skyweek from Sky and Telescope Magazine also presents a variety of astronomical events for the naked eye as well as telescope viewing. http://www.skyandtelescope.com/videos/skyweek

Lots of activities and information for families and novice astronomers.
