For centuries astronomers wondered whether they were clouds floating in the Sun's atmosphere, but we now know that they really are huge regions of magnetic field, about as intense as the field at the poles of an iron magnet. For some reason the field slows down the flow of heat from the Sun's interior and keeps sunspots slightly cooler than their surroundings. ... Solar Eclipses . ...

The Sun is our nearest star and the source of energy for life on Earth. ... For centuries astronomers wondered whether they were clouds floating in the Sun's atmosphere, but we now know that they really are huge regions of magnetic field, about as intense as the field at the poles of an iron magnet. ... Such abrupt events were named solar flares , and what made them especially interesting was that occasionally, after a prominent flare, a magnetic storm would erupt on Earth. ...

... Because of the need to schedule observations as efficiently as possible, the order in which exposures are executed may be different from the order in which they appear in the observer's Phase II submission-unless an explicit special requirement dictates otherwise. ... Data files can then be associated with the corresponding exposure line in the Phase II proposal by comparing exposure information in the Phase II proposal with data file header keywords. ... Time_Per_Exposure . ...

... Today this year's largest group of sunspots will cross the Sun's central meridian. ... The next day, the number of spots in the group reached five, and the day after, on June 2nd, it was possible to count thirteen sunspots on solar disk, which had been clear prior to this. ... This year's two most powerful active areas, which passed across the solar disk at the beginning of May, 2009, are set to appear in the Sun's eastern sector in two days, on June 6th. ...

... Meade Instruments Corporation . ... Refracting telescopes (Meade Models NG-60, NGC-60, DS-2070AT, ETX-70AT, LXD55-AR5, LX55-AR6 ) and mirror-lens telescopes ( ETX-90AT, 105AT, 125AT, LXD55-SC8, 8LX90, LX200 GPS Series ) are generally more versatile in a wide array of land and astronomical applications. ... The intermediate-level observer, or the non-casual telescope user who wishes to purchase one telescope for a lifetime, should consider a Meade Model LXD55 series, 8LX90, or LX200GPS. ...

... Observers looking at an object that is moving away from them see light that has a longer wavelength than it had when it was emitted (a redshift), while observers looking at an approaching source see light that is shifted to shorter wavelength (a blueshift). ... By measuring the amount of the shift to the red, we can determine that the bright galaxy is moving away at 3,000 km/sec, which is 1 percent of the speed of light, because its lines are shifted in wavelength by 1 percent to the red. ...
