Though the Sun seems to be taking a good rest and not showing off the sunspots, it does have some beautiful decorations here and there, for example, prominences or filaments, which are relatively cool materials hanging above the solar surface. This movie here shows a bubble forming under a prominence observed at the solar limb. The bubble displays a clear boundary between the prominence body. Small loop structures rise and are likely stopped at the boundary region.
