Mike - Proxima Centauri does rise above the horizon for a short time during the night from Hawaii although isn't visible to the naked eye. However, it doesn't get above 10 degrees above the horizon and observatories tend not to observe anything below about 30 degrees as it makes calibrations virtually impossible. 10 degrees might be physically impossible for most (it would be for UKIRT for instance).
