Partial Solar Eclipse: Astronomers past and present and Friends started gathering at 8am under cloudy skies. A glimpse of sunlight but nothing for First Contact. Then around 8.45am the Sun appeared and could be located in the 10 inch (with solar filter!). The ETX and filter was in use and all watchers had solar goggles. NMA created an amazing projection box and in this and the 10 inch the large sunspot was visible as well as the rugged edge of the Moon itself (mountains and valleys). Cheers went up as the skies cleared. Collinders were put to use and multiple images projected as planned. At 9am the pupils and CEB departed to join the whole College community on the XV Ruby pitch. 100s watched as the eclipse drew to a maximum, leaving a smiley face, aerial photographs were taken. The observatory continued to operate till Last contact at 10.38.59 UT. An experience to remember!

External vist: 20 pupils and 2 staff from the French exchange school near Versailles came up to the Dome. The afternoon sky was cloudy. All were briefed on the forthcoming eclipse and went away with solar goggles
