White Christmas




White Christmas, starring Bing Crosby and Danny Kaye, warms the hearts of all who watch annual Christmas specials. Sitting on their favorite easy chair in their cozy living room, they can romanticize all they want. But do they really crave a white Christmas? Or are their White Christmas dreams just a fantasy?
Old timers are often called snow birds, not because they fly north to enjoy a White Christmas, but because they head south for warmer conditions. Arthritic joints like it hot, while unstable old legs seek less slippery sidewalks. They look for a holiday where they can take a walk in the park without wearing heavy coats or boots.
If you had spent your first 20 years of life above 40 degrees of latitude, you might have a gentle view of snow. Munich, my hometown, is above the 48th parallel. That translates into seasons that include a healthy sprinkling of snow in winter. Most people know the downside of winter, i.e. avalanches, white-outs, ice storms, black ice, and icicles—big ones that kill. There are power outages, and falling trees and power lines, not to mention frostbite. Even I can remember walking home in the snow with my toes nearly falling off and then bracing for the bite of them warming up painfully. Those who have grown up in snowy conditions know to dress, how to stay indoors, and how to rev up the generator. They’ve learned to survive in conditions fit for an Eskimo. A wintry trip to Wisconsin renewed memories:

Soft sheets furrowed white
Diamond sparkles in light.
Sugar coated red pines
Iced branches and lines
Snow-angels, snowballs
Ice skating and fun falls

Comet Lovejoy Still Bright

Comet Lovejoy continues to burn. Currently in the Corona Borealis it is dimming from its earlier appearance in Leo. Nevertheless, the comet is still fun to follow as he moves through the different star fields. Today's ephemeris are:RA 16 05 08 and the Declination is +34 41 55
What do the numbers mean? RA stands for Right Ascension. That designation refers to longitudinal lines superimposed on the sky. In other words, the numbers given are written in hours, minutes and seconds.
Yes, you've guessed right--Declination is equivalent to latitude and is written in degrees. The listed positions puts the comet squarely between  Kappa and Tau, the two stars on the upper border of the Corona. Both stars shine at nearly 5th magnitude.  The comet itself is dimmer. If you would like to follow the ephemeris which are calculated cometary orbits here is the link:

Here's a page of Edmund's Mag 6 Star chart. It shows the RA and Dec. The pencil marks are the comet's position as seen two days ago.
