Perigee Moon - 3/19/2011 - 22:29:18 EST; copyright © reserved 2011, Richard Lovison

The weather cooperated tonight so I took this image at 22:29:18 eastern daylight time. Last nights Moon was just before full Moon and this one was slightly after as the official full Moon took place at 2:10pm, March 19th.

Perigee Moon Eve

Full Moon 3/18/2011 - 21:29:57 EST; copyright © reserved 2011, Richard Lovison

A perigee full Moon will occur tomorrow afternoon, March 19th, at 2:10 p.m. eastern daylight time. At 3 p.m. the Moon will be at a distance of 221,565 miles from the Earth, the closest distance in 2011. The last time this occurred was in March of 1993.

The Moon varies in size when viewed from the Earth due to the elliptical orbit of the moon with the Earth located off-center, closer to one side of the ellipse.

The above image was taken with an Olympus E-3 coupled to a Takahashi FC-60 refractor (1000mm, 35mm equivalent). The exposure was 1/125 sec, f8 at 100 ISO.

This is an image of a waxing gibbous moon taken this evening after a heavy rainstorm had cleared. It was captured with an Olympus E-3 coupled to a Takahashi FC-60 telescope (500mm, f8 objective – 1000mm using the E-3) mounted on a tripod. The exposure was 1/40th of a second at f8 with an ISO of 100.

Online Astronomy Courses

Wednesday, March 5th, 2008

I came across a site at the Massachusetts Institute of Technology where one can view or download courses on-line called MITOPENCOURSEWARE . There were three courses in astronomy that caught my attention so I thought I’d pass them on.

They are as follows:

These courses are offered for no charge though college credit is not given upon completion. Still, in my opinion, they are quite a valuable resource.

The three courses I mentioned offer a syllabus, study materials and assignments and the last course even includes a complete set of lecture notes. These are definitely worth a look for anyone having an interest in astronomy.
