Namely, the notion that a spectacular and brilliant fireball MUST be observed by a large number of people, that this is a necessary part of an observation for it to be accepted as a meteor. Multiple reports may be not be a valid criterion. I base this strictly on my own experience. On June 30, 1969, I observed a daylight fireball that was roughly half the brightness of the Sun (I haven't calculated that as a magnitude but that's really bright, okay?). I was working in my garden between 4:00 and 4:30 in the afternoon; it was bright cloudless day. What made me look up was that everything vertical had suddenly acquired two shadows: its "normal" one and a secondary shadow, about half as dark as the normal shadow, turned to the north by about 30 degrees, and that the secondary shadow was rapidly rotating further to the north! It took me about a second or two to realize what was going on and fall over on my back so I could look straight up and see a daylight fireball whose "head" was literally too bright to look at directly, traveling from WSW to ENE, leaving a bright trail about 120 degrees long! (Much later, based on the date and the track of the meteor, which passed through Taurus, I decided it was probably a beta Taurid.) I did not see a terminal burst and there was no sound, so it must have been high and fast. It passed beyond the eastern horizon. The next day, tremendously excited by what I had seen, I asked my co-workers if they had seen it (I worked at a university at the time). No one had. I asked friends, acquaintances, near-strangers. No one had. I called the local newspaper to see if anyone had reported anything. No one had. Eventually, I began to call newspapers west and east of my location, town by town, inquiring about reports. There were none. I called other universities, amateur astronomy groups, the U.S. Air Force, anyone that might have received a report of an aerial phenomenon. I spent four months, off and on, trying to find even one other report across a four-state area, filling three spiral notebooks with logs of my contacts, lists of calls to make, and so forth, without ever turning up a single report. Although I doubt very much that I was the only observer, from the standpoint of an official or unofficial record, there is none. If you note the date (6/30/1969), it was at the time of the Apollo 11 mission and so it occurred when the public mind was "primed" to be aware of things astronomical as they possibly could be. I concluded the human species is a) not very observant, or b) not very curious about what they do observe, and c) of a mind not easily stimulated by remarkable events and thoroughly mired in the trivia of the everyday. While I don't know if the Wales photos are a meteor or not, I don't think the "nobody else saw it" argument is a particularly strong one. From my experience, it might not be remarkable that a daylight fireball was not observed or reported by "thousands" of people, even if it was bright, spectacular, easily visible, screamed for attention, made loud noises, had a trail that twisted and skywrote the word "METEOR" in letters of fire across the heavens... Well, you get the idea. Sterling K. Webb Received on Sun 05 Oct 2003 03:17:34 AM PDT |
