Enter the search parameters for asteroids reaching brightest during the chosen month and year. In most cases, opposition and date of brightest are within a few days of one another. However, for some NEAs,the two dates could be weeks or months apart and the NEA could have up to three oppositions during a given apparition.
To avoid causing a server timeout when selecting all months for a year, make sure to apply one or more filters. "All" with no filters returns a maximum of 200 records.
The filters are applied with Boolean AND, i.e., all conditions must be met.
