Effect of solar X-ray flares on VLF radio wave signal strength at 19.8 kHz and 24 kHz received at Khatav in India.
Detecting solar radio bursts (solar flares) by continuously measuring the intensity of VLF radio signals and observing ionospheric propagation effects on radio waves. The high-energy radiation of solar flares (e.g. X-ray radiation) modifies the structure of the lower ionosphere at an altitude of 60 - 150 km/ 35-95 miles. The changed conditions for radio wave propagation are immediately measurable as variations of the receiving intensity on a Very Low Frequency radio receiver.

Earth's ionosphere reacts to the intense X-ray and ultraviolet radiation released during a solar flare. The ionospheric disturbance enhances VLF radio propagation. By monitoring the signal strength of a distant VLF transmitter, sudden ionospheric disturbances (SIDs) are recorded and indicate a recent solar flare event.

X-ray astronomy looks at X-ray wavelengths.
Different X-ray wavelengths show the structure of an explosed star.
This supernova remnant is located in the outer space formation known as the Small Magellanic Cloud.
This image combines X ray and Optical images to show details that would be hidden without both images.
A combined X-ray and Optical image of the exploded star named 1E0102.2-7129 ("E0102") seen by 2 telescopes in space.
The X-ray image in this photo.
The image includes X-rays from the the exploded star named 1E0102.2-7129 ("E0102") seen by the telescope in space known as the Chandra X-ray Observatory.
In the X ray image:
The lowest frequency X-rays (lowest energy X-rays) are shown in orange,
Medium frequency X-rays (medium energy X-rays) are shown in cyan and the
Highest frequency X-rays (highest energy X-rays) are shown in blue.
The Optical (visible light) image in this photo
The image includes Optical visible light from the same exploded star seen by the telescope in space known as the Hubble Space Telescope.
The Optical (visible light image) is in red, green and blue and show additional structure in the remnant and also reveals foreground stars in the field.
This data gives new information about the geometry of the remnant and the nature of the explosion.
A massive star (not visible in this image) is illuminating the green cloud of gas and dust to the lower right of the image. This star may have similar properties to the one that exploded to form E0102.

How to build a radio station in Somalia.
How to build a radio station antenna in Somalia.
The completed antenna in Galkayo, North East Somalia.
The Radio Free Somalia (“Free for all to use” known later as Radio Galkayo) antenna became a new sky line of Galkayo in August 1994.
The Photo was taken on the Galkayo to Bosasso highway, south of the Galkayo Police station, Galkayo, North East Somalia.
In 2009 this antenna is still a landmark of Galkayo, located on the main highway at Galkayo Police station although Radio Galkayo has moved out of the Police station and into its own building complex in central Galkayo. The antenna remains in its original location because it is too large to relocate.
North East Somalia became the Puntland State of Somalia on the 1st August 1998.
