A fledgling SWAN
Chris Schur from Payson, Arizona
Comet C/2025 F2 (SWAN), discovered March. 29 by amateur astronomers in public imagery taken by the Solar Wind Anisotropies (SWAN) camera on ESA’s Solar and Heliospheric Observer (SOHO) spacecraft, has reached magnitude 7.5. This imager caught the comet on April 8 in the morning sky with an 8-inch RASA scope and 22 minutes of exposure with a one-shot color camera.
