The brightening was caused by a rapid expanding of the star's outer layer - making this celestial body (at the maximum size) the brightest star in our Galaxy, with a radius comparable to the orbital radius of Jupiter... (originally the star was approximately 5 times larger than our Sun).
The dynamics of brightening are totally unique, and pretty much unexplainable: multiple sharp bursts (with phenomenal speed of expansion), followed by weird lulls.
The most interesting possibility is that V838 Monocerotis may have swallowed its giant planets.
"If one of the planets entered into the atmosphere of the star, the stellar atmosphere would have begun slowing down the planet, releasing more kinetic energy into the star. The star's envelope would then warm up enough to trigger deuterium fusion, which would lead to rapid expansion. The later peaks may then have occurred when two other planets entered into the expanded envelope." (source)

A Legendary Umbrella Shop in London
"Our man in London" Mark Obstfeld points the way to the world famous James Smith and Sons Umbrella Shop, which was founded in 1830 and is still owned and run as a family business. For 175 years the company has been making umbrellas, sticks and canes for both ladies and gentlemen and their reputation as the home of the London umbrella is well justified.
"The historic and beautiful shop is on New Oxford Street in the heart of London's West End and is a stunning reminder of the Victorian period. It is a perfect example of Victorian shop front design and has remained virtually unaltered in 140 years."
"The business in umbrellas has always thrived - perhaps because of the English weather, but also because of the outstanding reputation the company has for new umbrellas and their repair service... Much of the business for sticks comes from America where there has always been a shortage of good sticks and canes. One client even asked the company to make him a stick in every English wood possible - he received over 70 sticks in total!" (more info)
