An entity channeled by George Van Tassel as described in I Rode in a Flying Saucer (1953).
A particularly revealing transmission by Ashtar occurred on March 20, 1953:
I am authorized to inform you, we are in constant communication with our people we have in your national capitol. You will be hearing of an increase of phenomena resulting in many hallucinations, so-called, by your people. We have been in your immediate vicinity. I repeat. Do not be alarmed by unusual occurrences around you. We are now over your Mississippi River and now we arrive in your city of San Francisco…. Our plans are taking shape. Be prepared for anything. My love. I am Ashtar. Discontinue.
