Made of rarefied gas heated to millions of degrees, with its atoms highly ionized (stripped of electrons), the corona gets sculpted into streamers and loops by the Sun’s powerful magnetic field and shines with a light seen nowhere else. Those who have witnessed it say it is hauntingly beautiful and one of the most awesome sights in all of nature. During those moments of totality, it is safe to look directly at the Sun, even through binoculars or a telescope. But whenever any part of the photosphere is uncovered, it is essential to view the Sun through a safe solar filter, that is, one that meets the transmission requirements of the ISO Spec 12312-2, sometimes labeled as: 12312-2:2015 which is an international safety standard. Such filters are widely available and are not too costly. Looking at the uneclipsed or partially eclipsed Sun through dark sunglasses or any other unapproved filter is a recipe for serious and potentially permanent eye injury (i.e., do not use regular sunglasses).
