A little over a year after <a href=\"https:\/\/splendeurs-du-ciel-profond.blogspot.com\/2025\/07\/sn2025rbs-une-supernova-cote-du-noyau.html\" target=\"_blank\" rel=\"noopener\">SN 2025rbs<\/a>, a new supernova was discovered on <strong>September 1, 2026<\/strong>. It is named <strong>SN 2026aaiv<\/strong> and it, too, appears very close to the central nucleus of this spiral galaxy.<\/p>\n<h2>Photographed from Marseille with the S50 Pro<\/h2>\n<p>I was able to take a picture of it from Marseille with my <strong>The Seestar S50 Pro has just arrived<\/strong>. This is a great target to start enjoying this little telescope! Photographing a supernova in another galaxy is definitely doable with a smart telescope.<\/p>\n<p>To locate SN 2026aaiv in your images, look for a small bright spot near the nucleus. A reference image taken before it appeared will help you clearly see what has changed. That\u2019s exactly what makes this exercise so interesting: this tiny spot tells the story of a massive event.<\/p>\n<h2>A rapidly evolving outbreak<\/h2>\n<p>To provide a specific date as a reference, the observations by Jean-Claude Merlin published by the Soci\u00e9t\u00e9 astronomique de France indicate a magnitude <strong>13.9 in the V band on September 4<\/strong>, then <strong>12.0 on September 10, 2026<\/strong>. It has therefore become significantly brighter between these two measurements. Before attempting to capture an image, check recent observations rather than relying on a fixed magnitude.<\/p>\n<p>If you're looking for a target with your smart telescope that's a little different from the usual classics, NGC 7331 is well worth checking out. From Marseille, the S50 Pro allowed me to capture a very vivid image of it.<\/p>\n<p><small>Sources : <a href=\"https:\/\/physics.purdue.edu\/brightsupernovae\/sn2026\/sn2026aaiv.html\" target=\"_blank\" rel=\"noopener\">SN 2026aaiv Data Sheet and Monitoring<\/a> ; <a href=\"https:\/\/saf-astronomie.fr\/activites-adherents-images-ciel-profond\/\" target=\"_blank\" rel=\"noopener\">Observations by the French Astronomical Society<\/a>.
