C-Class H-Alpha flare was seen stringing out from the solar disc from AR-2324. We Stayed until 3PM sharing views with about 60 people walking or biking the Los Gatos Creek Trail. Happy Astronomy Day, stellar cheers and enjoy the below pics.

April 2015 Lunar Eclipse Shots

Member April 2015 Eclipse Shots

Members, send us one or two of you lunar eclipse photos (max size 720×1280) to packer at yahoo dot com and we’ll post here. People shots welcome!

“look for oranges, reds, greys and turquoise

The source of the turquoise is ozone. During a lunar eclipse, most of the light illuminating the Moon passes through the stratosphere, and is reddened (can look orange) by scattering. However, light passing through the upper stratosphere penetrates the ozone layer, which absorbs red light and actually makes the passing light ray bluer” This can be seen as a turquoise fringe around the red.
