| Comment | After reading a report on the sohohunter group that comet 17P is visible in SWAN images, I decided to take a look for it this morning. It's there, although it wasn't easy. Low elevation, early twilight, and the fact the comet was quite close to an 11th-magnitude star, all conspired to make the observation more difficult than it otherwise would have been. |
