National Astronomy Week event: The evening was clear and mild. The NAW event was advertised widely on internet and radio and combined with the planned Friends 'Spring Sky' event brought visitors from a wide geographical area. Some 70 came up to the dome of all ages, some very little. Bright stars were identified. With RDMs help 2 ETX 105s were in operation, looking at Jupiter, the First Quarter Moon and Orion nebula. Binos looked at the Pleiades. The 10 inch initially viewed the Moon with a filter and showed super detail, especially near Cassini and Mt Piton being illuminated on the dark side of the Terminator. After Culmination, Jupiter was followed in the western sky and showed increasinglty more bands during the evening. Orange Io closed with the planet as we observed and went into Occultation at 10pm. Mars was seen to rise at 9.30pm and was viewed for the first time this year in the ETX

Despite the twilight, Jupiter was viewed well in the 10 inch and 4 moons and 4 cloud bands easily seen. The second group had a darker sky and saw a couple of satellites. Jupiter now showed 6 bands and orange Io was seen to close with Jupiter ready to pass behind the planet. The Pleiades were viewed in the Binos. By 8pm the sky had clouded over

Solar observing: The 10 inch viewed the Sun for the first time in a while and the plethora of sunspots was seen, including the active groups which have given rise to the recent flares
