Back to the Double Star page
Likely a previously unknown double star.
The light curve graph shows the steps as the stars reappeared from behind the Moon. With it we can get an approximate magnitude for the companion and if another observer or observers were capable of recording this event far from me at another position on the Moon limb a position angle for the two stars can be determined.
