Prof. David G. Iadevaia maintains his private observatory near Sabino Canyon. On Tuesday night the AllSky Camera he designed and built recorded the fireball which lit up the partly cloudy sky and produced a sonic boom heard over much of the area. Attached find a short video clip of the event. Prof Iadevaia retired from Pima College this past summer after 30 years of teaching Astronomy and Physics.

Prof. Iadevaia and Linda Proctor, take you on expedition to SP Crater near Flagstaff, AZ to view the 20 May 2012 annular solar eclipse. Using various cameras, telescope and appropriate filters they document the eclipse in video as well as still images. SP Crater is a cinder cone volcano about 7 miles in from highway 89. The eclipse was annular for about 2m13s. The approximate GPS coordinates for the observing site was 35.5762N and 111.571W. One experiment was not performed because of high winds. The HD video camera was not flown.It was a successful expedition and Linda, once again was a valuable assistant and photographer.

Prof. Iadevaia shows how to use a pair of binoculars and a tripod to view the Sun. With the upcoming Solar Eclipse and transit of Venus, this method will work very nicely. Never look directly at the Sun with either a telescope or binoculars useless the appropriate filters are used. This method is a projection method and is very safe.
