Citation for renaming Asteroid “260824”” to “Hermanus”

Discovered by Prof. David Trilling

Hermanus  260824   South African city
(260824) Hermanus = 2005PC24

Discovered 2005 August 10 by D.E. Trilling in the course of the Deep Ecliptic Survey.
The village Hermanuspietersfontein, later shortened to Hermanus, was founded in honour of a man who taught Dutch to farmers’ children. This asteroid is named in recognition of the Hermanus Astronomy Centre’s enthusiasm for astronomy and their dedication to educational outreach in South Africa.
