     Scientific Officer of the Hong Kong Observatory, Mr Woo Wang-chun, said, "If weather permits, a bright and clear moon can be observed from open space in all districts during the period. Although the moonrise occurs after the full moon (i.e. when the moon and the sun are located on opposite sides of the Earth, see the attached diagram), the brightness of the moon will not diminish after the moonrise and moon-watching will not be affected."

     For information about the weather during the Mid-Autumn Festival period, please refer to the "7-day Weather Forecast" issued by the Observatory at www.weather.gov.hk/wxinfo/currwx/fnd.htm.
