In 1977, Uranus occulted a star, and the starlight flickered 40 minutes before and after the actual occultation, revealing Uranus' rings.
This is common knowledge to astronomers, but what I can't find out is which star Uranus occulted. Can someone give me the name of this star?


From wikipedia, the rings of uranus

The definitive discovery of the Uranian Rings [...] use[d] the occultation of the star SAO 158687[...]

The star SAO 158687, also cataloged as HD 128598 is a magnitude 8.7, orange dwarf star in Libra. There seems to be nothing special about the star, except that one day, a planet passed in front of it.
