- Late Evening session (4.0 hrs duration).
Moderate seeing- Session operated under semi-automated control, with remote monitoring from indoors computer. - Ambient Temperature: -5.0°C (minimum) - CCD operation -30°C (at 58% average cooling). - main objectives of the session were to acquire images of selected project stars for ongoing photometric and astrometric analysis, opportunity was taken to acquire a series f images of the PHA 4179 Toutatis during its 2012 flyby of earth at ~ 18 lunar distances. -
(4179) Toutatis Flyby |
Discovered in 1989, 4179 Toutatis
is a potentially hazardous asteroid (PHA) that passes by Earth’s orbit
every 4 years. The next time Toutatis will approach at
least this close to Earth is in November 2069, when the asteroid will
safely fly by at |

Opportunity was taken to acquire a series of CCD images of Toutatis through my LX200 telescope during part of the flyby. |
