Solar flares, sunspots and prominences are features of the sun that have some effects on Earth: 1. Sunspots- Dark areas around the surface of the sun that are cooler than surrounding areas. They appear and disappear over a period of time. The period from minimum to maximum number of appearances of sunspots is the sunspot cycle, which occurs every 11 years. Sunspots are believed to have effects on Earth's weather and climate. Low temperatures in some countries and drought in other countries were observed during a period when very few sunspots appeared on the sun's surface. 2. Prominences- Arches of gas that rise from the sun's surface and flow back to it caused by magnetic fields of sunspots. Some prominences are in the forms of loops, curtains, or funnels. Solar prominences may last for many hours and can extend millions of kilometers above the surface of the sun. 3. Solar flares- Violent eruptions that are suddenly released and are caused by magnetic energy stored in the corona. Ultraviolet light and X rays from solar flares cause disruption of radio signals, making communication by radio and telephone difficult. Magnetic storms occur on Earth when electrically charged particles from the corona and solar flares ae added to the solar wind produced by the corona. When this happens, Earth's atmosphere radites beautiful lights called aurora borealis or northern lights. This same light is called the aurora australis in the Southern Hemisphere.

About 2 million mph. Pretty Fast ! That answer may be referring to "coronal mass ejections" rather than the closely related phenomenon of solar flares.
Sunspots are believed to be the sites where solar flares are generated. Sunspots are known to be "storms" on the sun's surface, but they are not yet fully understood.add The surface of our Sun is about 5800 deg C and above, and naturally most of the material is highly ionized. Thus large electrical currents may be generated, and these in turn cause the magnetic field loops seen as solar activity. These magnetic loops can accelerate the charged ions from the Sun, hence the name Solar Flare..
Not exactly. They are detectable when they occur, before the Sun revolves to place them in a position that may affect the Earth.
Not at present. It may, at some point in the future when we understand more than we currently do about the inner workings of the Sun, become possible to predict flares with some precision. But currently, flare prediction is more guesswork and luck than science.

Solar prominence are seen in the photosphere of the sun that goes further in the corona. These prominences can reach out over thousands of kilometers.

Solar flares mainly consist of helium and hydrogen ... these two gases are the energy suppliers in solar flares .... when solar flares fall on the surface of the earth then due to friction the atomic bond becomes unstable and the gases FUSE and explosion occurs.. usually solar flares have 10 raise to the power 32 ergs of energy ..
Solar flares are sudden brightening of the sun caused by ejection of huge energies. Solar flares will most likely not affect the colour light because solar flares produces radiation across the electromagnetic spectrum at all wavelengths, from radio waves to gamma rays. Thus, it is difficult to view solar flares on the visible spectrum and must be viewed with special instruments.In other words, photons (light particles/waves) from a solar flare are emitted at all frequencies along the electromagnetic spectrum and must be viewed with special equipment. Unless the solar flare interacts with anything else (maybe other atmospheres), they don't change the colour of light.

You may be thinking of a Coronal Mass Ejection (CME). A chunk of the Sun's outermost layer flies off toward Earth. We had one a couple of weeks ago, producing auroras in parts of the world that are usually too southerly to see them. Also, you may be referring to the closely related phenomenon of "solar flares". Flares are certainly a "solar feature" and are connected with the solar wind.
