Observing Notes

Harold Corwin

IC 799 = NGC 4520. WH's position precedes the galaxy, while Swift's follows it; this probably accounts for Swift's belief that he found a new nebula. Both observers noted stars involved with or close to the galaxy. WH probably mistook the nucleus as one star and picked up the one just to the west as his second, while Swift suspected only that western star.
