The Sun giving out a large geomagnetic storm on 1:29 pm, EST, 13th March 2012
Hey Everybody!!!! Come On In-
I found some new views from the old Sun!! And a great Feature Presentation Video for our viewing pleasure tonight.
Welcome to the new people coming in for the first time! This Nature Blog is a collection of posts generally regarding the Nature of Mother Earth, Father Space or Human Nature! Each post is a different subject, so if you do not care for one, try another from the selection on the right. You can also subscribe by email if you want notification of the posts (or friend connect Google Reader).
We are enjoying a world tour through You Tube Videos. I gather information from the internet pertinent to each subject, however, learning is completely optional. It is my hope that my Grandchildren will come to the Blog when they are old enough to read!
Tonight our journey takes us to the Sun. I thought it would be nice to Light Up Your Life!!! Enjoy your photostudy.
