All throughout Tuesday and Wednesday (August 3-4), skywatchers at the North Pole will get a real treat. Space weather experts say that the number and intensity of auroras that will appear during these two days will be unusually high for this period. This is due to the fact that a solar eruption took place late Sunday, which spewed a lot of material and radiation from the Sun our way. When this wave of matter hits, most of its will flow alongside Earth's magnetic lines, causing the aurora events to intensify, Space reports.
“This eruption is directed right at us and is expected to get here early in the day on Aug. 4th. It's the first major Earth-directed eruption in quite some time,” says Harvard-Smithsonian Center for Astrophysics (CfA) expert Leon Golub. The expert adds that during the Sunday eruption, countless tons of plasma material – ionized atoms were ejected. Most of that matter is heading our way, and will hit our magnetosphere shortly. The coronal mass ejection (CME) that gave rise to this situation was discovered with the NASA Solar Dynamics Observatory (SDO), a space telescope whose sole job is to keep an eye on the Sun. “We got a beautiful view of this eruption. And there might be more beautiful views to come if it triggers auroras,” Golub explains. The SDO is NASA's most advanced solar observatory to date. It's able to keep track of the star's action on several wavelengths at the same time, and is especially well suited to observe variations that occur at the extreme ultraviolet (EUV) wavelength range. At this point in time, the Sun is acting up in a particularly weird manner. Generally, the star “acts” in 11-year-long cycles, which culminate in periods of solar maximum, and minimum, respectively. But, for the past couple of years, it has not exited the solar minimum stage. At the end of 2009 and the beginning of 2010, the Sun began showing signs of activity, but the number of CME and solar storms it experienced thus far is still well below normal.

Solar EUV lines are due to radioisotopes produced by Uranium fission, according to the following peer reviewed paper. Radioisotopes cause a new class of room temperature atomic spectra of solids (radioisotopes and X-ray sources) by a previously unknown phenomenon. X-ray sources can be radioisotopes that emit predominantly characteristic X-rays.

UV dominant optical emission newly detected from radioisotopes and XRF sources,

ABSTRACT
The current paper reports first and definite experimental evidence for gamma-, X-, or beta radiation causing UV dominant optical radiation from (1) radiochemicals such as 131-I; (2) XRF sources such as Rb XRF source present as salts; and (3) metal sources such as 57-Co, and Cu XRF sources. Due to low quantum yield a need arose to develop two techniques with narrow band optical filters, and sheet polarizers that helped in the successful detection of optical radiation. The metal 57-Co spectrum observed at room temperature hinted that it could be optical emission from excited 57-Co atoms by a previously unknown phenomenon. In order to explain UV emission, it was predicted that some eV energies higher than that of UV, termed temporarily as Bharat radiation are generated within the excited atom, while gamma-, X-, and beta passes through core-Coulomb field. In turn, the Bharat energy internally produced within the excited atom causes UV dominant high-energy spectrum by valence excitation. As excited atoms become free from surrounding unexcited atoms by valence excitation, room temperature atomic spectra of solid radioisotopes and XRF sources became a possibility. It implies existence of temporary atomic state of solids. The experimental evidence that gamma-, X-, and beta radiations causing UV dominant optical emission from within excited atoms of radioisotopes suggests the possibility for solar gamma-, X-, and ß radiations causing EUV by the atomic phenomenon described here.

These observations, if really true, provide very valuable information to solar physics, and Einstein’s mass-energy relation.
Solar flare constitutes X-rays, gammas, betas, neutrons, fission fragments from Uranium fission. Probably, solar eruption was seen late Sunday at X-rays. However, fission fragments (radioisotopes) took 2 or 3 days to reach that place. This is due to the fact that gammas or X-rays reach faster than EUV. Neutrons, and radioisotopes take 2 or 3 days because of their mass. Please peruse my comment (27198): A FRESH INTERPRETATION OF EINSTEIN’S MASS - ENERGY EQUIVALENCE http://www.nature.com/news/2011/110922/full/news.2011.554.html
Most colorful auroras seen at the North Pole might be direct evidence from nature to Padmanabha Rao Effect causing optical emission from radioisotopes. Possibly, along with cosmic rays even fission fragments (radioisotopes) may be abundantly reaching to North and South poles. Depending upon the ionizing radiation energy of γ, β or X-ray the colors are formed in auroras by Padmanabha Rao Effect. Low ionizing radiation energy may cause an aurora displaying dominant EUV and UV along with low visible light and infrared radiations. However, if the energy is relatively high, aurora may show bright yellow, green, and blue colors besides infrared radiation, with low EUV and UV intensity. Colorful auroras might suggest that light and heat are partly from fission products (radioisotopes) reaching Earth.raomap@yahoo.com
