In this instance, a temporary affair going by the video – which may change. At https://spaceweather.com on September 6th, we learn that Comet Nishimura on its journey towards and around the Sun, was struck head on by this week’s CME event. Blasted by the solar wind. The comet is currently half way between Mercury and Venus. A goodly chunk of its tail is now missing – ripped asunder by the elctromagnetic effects of the Sun unleashing a burst of energy. You can see the videa at the link, taken by astrophotographer Michael Jaegerr from Martinsberg in Austria. Back in 2007 Comet Encke had an even bigger encounter with the solar wind.
