The light curve chart below shows the estimated development of the minor planet's magnitude.
The all-sky chart below shows the path of the minor planet over the same period as the light curve. The current position is marked yellow.
The following chart shows the path of the minor planet in the next few days. The field of view is optimized for (~10x50) binoculars and finderscopes.
