Watching the solar corona online

The solar eclipse on August 21, 2017, like the following may not be so rare for many of us.

The fact is that modern achievements of science and technology allow us to recreate the conditions of total eclipses, on any day.

The High Altitude Observatory (HAO) of the National Center for Atmospheric research (NCAR) is located in Boulder, Colorado, at the foot of the Rocky Mountains. HAO conducts research and provides community support and facilities in the following areas: Atmosphere, Ionosphere and Magnetosphere (AIM), Long-term Solar Variability (LSV), and Solar Transients and Space Weather (STSW).


I explain it in a simple language for a man in the street.

You can watch the eclipse in person or online.

On this page I will provide links to scientific resources on observing and studying the solar heliophysics.

Thanks to special technologies, scientists can completely close the solar disk and see the surrounding of the solar corona without the help of the moon.

Through this site you can observe the solar emission of the plasma and the variation of the magnetic fields, in other words, observe the solar corona.

You can choose any day and date, for example, a day in the past year or month, or today’s or yesterday’s date.


Also another site of the observatory. Big Bear Solar Observatory (BBSO)

It will be useful for obtaining images of the surface of the sun in very good resolution.

Big Bear Solar Observatory (BBSO) Solar flares signify the sudden release of magnetic energy and are sources of so called space weather. The fine structures (below 500 km) of flares are rarely observed and are accessible to only a few instruments world-wide. Using exceptionally high resolution images from the 1.6 m New Solar Telescope (NST) equipped with high order adaptive optics at Big Bear Solar Observatory (BBSO), we observed the long-enduring evolution of the M6.5 solar flare in NOAA active region (AR) 12371 on 2015 June 22 in unprecedented detail. We see the ribbon propagating eastward across the sunspots, the appearance of more and more post-flare loops which are filled with condensing chromospheric plasma, the clumps of chromospheric plasma falling toward the loop footpoints (coronal rain), and the fine-scale brightenings on the chromosphere when it is impacted by the condensed plasma. With Interface Region Imaging Spectrograph (IRIS) slit-jaw images in the near UV passband, we identified the brightenings which are virtually coinciding in position, time and duration with those in the NST H-alpha images. It seems reasonable to suppose that the H-alpha brightenings revealed by this observation are chromospheric counterparts to the UV brightenings in the transition region reported by Kleint et al. (2014). Compared to the previous IRIS observation, our observation captures the finer components in the deeper, cooler and more dense chromosphere during an M-class flare, and clearly demonstrates the cause-and-effect association between falling plasma and brightenings. We also measured the cross-sectional widths of the flare ribbons, the post-flare loops and the brightenings at the footpoints, all of which are generally on sub-acrsecond scales (less than 200 km). Our observation provides a novel information on the spatial scale of the energy transport and heating mechanism of solar flares.

All this will be useful for you if you need to save time and get the desired result.

For this it is no longer necessary to wait for solar eclipses to observe phenomena that are difficult to see.

It can prove to be much more exciting and instructive, since professional observatories.

Much of the western United States began the morning with the view of a super blue blood moon total lunar eclipse. In this silent time lapse video, the complete eclipse is seen over NASA’s Jet Propulsion Laboratory, located at the base of the San Gabriel Mountains near Pasadena, California. 

This Jan. 31 full moon was special for three reasons: it was the third in a series of “supermoons,” when the Moon is closer to Earth in its orbit – known as perigee – and about 14 percent brighter than usual. It was also the second full moon of the month, commonly known as a “blue moon.” The super blue moon will pass through Earth’s shadow to give viewers in the right location a total lunar eclipse. While the Moon is in the Earth’s shadow it will take on a reddish tint, known as a “blood moon.”
