Solar Observing Online

The sun will become more and more active as it the 11-year solar cycle swings from the slow and quiet to the loud and wild. You can follow along using some online solar observing tools. SOHO is still my favorite but Big Bear offers some excellent ground based views and the newer STEREO spacecraft has 3-D views and its own iPhone app!

SkyandTelescope.com – News Blog – The Big Dipper Adds a Star.

One my favorite targets for me and for star parties is the optical pair Alcor & Mizar and Mizar is also a binary system itself which is apparent through pretty much any telescope.

In reality each of the stars in the Mizar pair is a binary making the whole telescopic view a total of 6 stars when you include the star that also shows up in the field-of-view.

Recently astronomers at the Palomar observatory were looking for extra-solar planets using near-infrared techniques and discovered that Alcor also is a binary system! That makes a total of 7 stars when you look at that one spot in the Big Dipper. Read more over at SkyandTelescope.com

Tips for Viewing the Geminid Meteor Shower | Universe Today

Here are some tips for viewing the upcoming Geminid meteor shower from Sean Welton from Universe Today

Geminids 2009

Occurring every year in mid-December, the Geminid meteor shower is commonly referred to as the most reliable meteor shower of the year. That is, it almost always puts on a great show!

The Geminid meteor shower is sure to be a stunning show this year, as the Moon will not be visible at night, so its glow will not impede your meteor viewing ability. In addition, the Geminids’ radiant is favorably positioned for most viewers at this time of year. In order to see the most meteors, I suggest the following tips:

  • The Geminid meteor shower has a very broad maximum peak. Because of this, the night on which you view the meteors isn’t critical. You will of course, see more meteors on the peak nights. This year the Geminid meteor shower’s peak is the night of December 13th-14th, 2009.
  • The best time to view a meteor shower is in the late night to early morning hours. The best time to view a meteor shower typically begins around 2 AM. This is because as the Earth rotates toward dawn, the forward velocity of the planet adds to the linear velocity of the surface and atmosphere. This has the effect of “sweeping up” more meteors.
  • If you’re not normally awake at 2 AM, like many people, simply go to sleep very early and set an alarm clock to wake you up to view the meteor shower. Trust me on this point, it is definitely worth it.
  • The Geminid meteor shower’s radiant is right near the twin bright stars Castor and Pollux in Gemini. Click the image at top right to see a map (thanks to Stellarium). The trick, however, isn’t to look towards the radiant, but to keep your eyes on the whole sky. While it’s impossible to look at the whole sky, just keep your eyes scanning and alert. This increases your chances of seeing a fleeting meteor or one out of the corner of your eye.
  • Darkness is key to proper meteor shower viewing. If you live in a city or other light polluted area, try going to a dark sky site to truly experience a meteor shower. You might be surprised how close a dark sky site is to you! Here are some tips on finding a dark sky near you.
