| 説明 | AR 2297 is important to catch since it was the sunspot that ejected the CME that caused the strong aurora on March 17th. It has almost rotated away from us but just caught it on the Western limb of the Sun this AM. Its surrounded by an extensive area of light coloured faculae which is the only clue in white-light that there is a strong magnetic field around it.Celestron 1000/102mm refractor with Herschel wedge. TeleVue 2.5 x Barlow.Skyris 283m CCD camera.Ioptron ZEQ25GT mount.White light - false colour. |
