Observing Notes

IC 3688 = NGC 4633. Schwassmann's position is good, but it is 10 seconds of time following Swift's for NGC 4633 (actually found by his son Edward. Swift does not say who determined the positions for Edward's nebulae). The descriptions are similar, and Schwassmann has a note about the nearby star, just as Swift does.

The identity, apparently first suggested by Ames, is therefore secure.
