After hearing the news. We all rushed out side to take a look at it. Since we were eating inside in poor lid room of our office we were not able to have the clear glance at it at one short.

We can only see lost of tourist trying take its picture against the strong sun ray of high altitude Tibet. Some of our team member had to go in office to get their sun glass to have a better view. As we stand in sun for some time we are finally able to have a glance at the beautiful solar halo right above the Jhokhang temple. It looks as if like a huge auspicious umbrella  above the Temple. having about half an hour, this auspicious finally vanish into the atmosphere.

here is some detail information i found on Wikipedia.

A halo (from Greek ????, halos;[1] also known as a nimbus, icebow or gloriole) is an optical phenomenon produced by ice crystals creating colored or white arcs and spots in the sky. Many are near the sun or moon but others are elsewhere and even in the opposite part of the sky. They can also form around artificial lights in very cold weather when ice crystals called diamond dust are floating in the nearby air.

There are many types of ice halos. They are produced by the ice crystals in cirrostratus clouds high (5–10 km, or 3–6 miles) in the upper troposphere. The particular shape and orientation of the crystals is responsible for the type of halo observed. Light is reflected and refracted by the ice crystals and may split up into colors because of dispersion. The crystals behave like prisms and mirrors, refracting and reflecting sunlight between their faces, sending shafts of light in particular directions.

Atmospheric phenomena such as halos were used as part of weather lore as an empirical means of weather forecasting before meteorology was developed. They often do mean that rain is going to fall within the next 24 hours as the cirrostratus clouds that cause them can signify an approaching frontal system.

Other common optical phenomena involving water droplets rather than ice crystals include the glory and the rainbow.
