Custer's Weather...and other Clear Sky Charts

To have a good night for observing,
we need a dark, cloudless, non-hazy sky.

MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications). These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated,
global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.

 Some things to keep in mind when planning your visit to the Custer Observatory:

A Full Moon is BAD for observing - even the moon appears flat and washed out! The bigger the moon, the brighter it is and that bright moonlight washes out all the deep sky objects people normally come to look at. Generally, the less moon - the better.
Check this moon calendar.

Clouds, rain, fog are BAD. The hopeful sounding, yet vague "partly cloudy" usually means poor viewing that night. Just because you can see a few stars through the clouds doesn't mean it's a good night for observing. Looking at stars with the telescope really don't reveal much more than what you see just looking up at them.
