Astronomers on Earth have not been able to track the #comet for weeks because of the sun's glare. STEREO-A's movie is reassurance that the comet has not broken apart despite predictions to the contrary.

Astronomer Qicheng Zhang of the Lowell Observatory is optimistic about the comet's chances:"It continues to brighten steadily, and is now up to magnitude 7," he says. "It also continues to display a very robust ion tail. There are zero signs that the nucleus is disintegrating."

This is good news for sky watchers. If #Tsuchinshan-ATLAS can hold itself together just a little longer, it will become a naked-eye object in late Sept. and October. Zhang predicts "the comet will brighten to magnitude +4 ± 1 at perihelion on Sept. 27th, to a daylight peak of -3 ± 1 near inferior conjunction on Oct. 9th, and subsequently produce a quite possibly 20+ degree dust tail visible under dark skies (Oct ~19) before fading away."
