"Surely there is something in the unruffled calm of nature that overawes our little anxieties and doubts; the sight of the deep blue sky, and the clustering of stars above, seem to impart a quiet to the mind." Jonathan Edwards (1703 - 1758) |

Check the Clear Sky Clock for your city to see how viewing conditions are predicted tonight and tomorrow in your observing area! The Clear Sky Clock above is a great and pretty accurate tool for finding out about how your evening skies will be for observing. The darker the blue box, the better the observing conditions. To find the Clear Sky Clock for the skies in your area simply right click above anywhere in the Clear Sky Clock box. This will take you to a web page for the Grand Rapids Clear Sky Clock. From this page look to the right of the clock for a green box that says "Other clocks" and click on the word "All". From there it's easy to find the Clear Sky Clock for your observing area. I've used this since August of 2002 and found it to be a bit more accurate than the local TV weatherman. (Well.... I guess that's not too much of a surprise.)

The Moon Phases module that you see above is pretty simple in design, and self-explanatory, but it's a very handy tool all the same. Like the Clear Sky Clock above it's designer is generous enough to give it out as a freebie. You can get to their web site by clicking on the word "moon phases" on the module. |
The Weather Underground web site can be set up to find your local weather. They have different stickers that you can place on a web page for local weather conditions. I chose the one that displays rise and set times for the sun & moon, as these are the conditions that are related to astronomy observing.

Current Solar View MDI Continuum LASCO C2
EIT 171 EIT 195
The solar images above are courtesy of NASA and the SOHO (Solar & Heliosperic Observatory) project. They continue to update every few hours, every day. * The MDI (Michelson Doppler Imager) image will show sunspots. This image is close to what you would see with the naked eye. Just keep in mind that it is dangerous to actually look at the Sun itself with the naked eye. * The LASCO (Large Angle Spectrometric Coronagraph) image takes images of the solar corona by blocking the light from the Sun itself, creating a type of eclipse. This image shows the inner solar corona. * The EIT (Extreme ultraviolet Imaging Telescope) images show the solar atmosphere at different temperatures. The blue image shows the atmosphere at about 1 million degrees Kelvin. The green image, about 1.5 million degrees Kelvin. Just click on one of the photos to go to the SOHO web site for many more updating photos, and tons of great information.
