Asteroid 5181 SURF was discovered on April 7, 1989 by Eleanor "Glo" Helin at Palomar Observatory near Pauma Valley, California. It has a period of 3 years, 270 days. Helin named it for the Summer Undergraduate Research Fellowship at the California Institute of Technology(Caltech), including some students who participated in asteroid discovery.
The astrological meaning of SURF, however, appears to be much less profound. "To surf" may mean just that, or it may mean "to flit from one activity to the next, to move rapidly through something", as in "channel surfing"(flipping rapidly through TV channels in search of something interesting) or "Net surfing"(browsing through web sites). Skimming over something; giving superficial, cursory, minimal, reluctant or lukewarm attention to something(perhaps when closer attention is called for); making shallow or snap judgments; being emotionally shallow, impatient or addicted to excitement; having little patience with or time for something seems to be the meaning of asteroid SURF; also possibly water sports conducted on tthe water's surface, such as sailing, surfing or swimming. I have not studied SURF in the charts of those who are into skateboarding and related extreme sports, but SURF may very well relate to these also. I don't mean to dump on those who are into these sports; everybody has a SURF in their chart.
Earl Warren, a former conservative government official who advocated locking up "the Japanese" on the US mainland during World War II, later became a liberal activist Chief Justice of the US Supreme Court, and then headed the commission investigating John F. Kennedy's assassination, whose report is widely disbelieved. During the 1950s, bumper stickers reading "Impeach Earl Warren" were widely seen on cars in America due to the decisions his Supreme Court handed down, like Brown vs. Topeka Board of Education. Some reactionary elements still find these decisions of Warren's inconvenient, if not actually deleterious to society. He has SURF out of bounds, conjunct Hammurabi(harsh measures), semisextile the Moon(the public), undecimal Antigone(standing on principle), sextile the Vertex(significant relationships--like the one Warren had with Franklin Roosevelt), square Mercury(writings, thoughts, the media), tredecile Jupiter(the law); trine Damocles(challenging the system, drastic change, drama), Nessus(the predator), Roachapproach, Thetis(producing something new and better, being reminded of one's vulnerability), and Torricelli(in the eye of the storm); annd biquintile the East Point(the way the world sees you).

The glyph for SURF is my creation.
