These videos are an interesting foray into the facts, sizes, distances and precautions involving the Mercury transit across the face of the Sun on Monday.
Number 1, Do not look directly at the Sun. Mercury is too small to see with the naked eye, and will not blot out significant portions of the body of the Sun, which sometimes happens with solar eclipses.
Number 2, You will need a telescope to see the perfectly round spot of Mercury moving across the face of the Sun, but you will also need an appropriate solar filter to step down the power and intensity of the Sun. Talk to someone from your local astronomy club as they are usually more than willing to help the general public have a look.
The following is the astrological definition of ‘combust’, an alignment indicating that two planets are very close to each other.
Combust: Said of a planet when in extreme closeness to the Sun, the limits variously placed at from 3° to 8°30′. The characteristic effect to which the term applies is probably confined within an arc of 3° and is more pronounced when the planet rises after the Sun. Older authorities, including Milton, have described it as weakening, except in the case of Mars which was said to be intensified. The probabilities are that the effect of the combust condition is to combine the planet’s influence more closely with that of the Sun, until it is no longer a physical emotion capable of independent control, but an integral part of that consciousness of Destiny that the Sun imparts. Thus Mercury combust imparts to the mind a capacity for concentration upon what it deems its own destiny, but robs it of its receptivity to distracting or diverting influences. Hence it is no bar to the achievement of its own objectives insofar as the ability to achieve them is within its own powers, but it robs the native of the cooperation of those whom he alienates by his particular species of obtuse deafness to any or all argument that runs counter to his own concepts. Edison and Kant both illustrate this interpretation. Venus combust may take away the strength to achieve, but when in a particularly close conjunction with the Sun it produces the condition sometimes termed nymphomania – described by Bolitho concerning Lola Montez. Mars combust is always the man who fights for what he wants; and so with each planet according to its intrinsic nature.
This NASA video, complete with many details, may be found on YouTube. In Greek mythology Mercury (Greek Hermes) stole the cattle of, and became fast friends with, Apollo, the Lord of the Sun, giving to him the lyre, which he had just invented earlier that morning.
Not bad for a one day old infant.
All of which goes to show that the Sun and Mercury have been buddies right from the start, never far from each others side.
