Oct 24/25 Meteors
October 25, 2008 4 Comments
The Orionids are still producing a healthy number of meteors. The number of detections from Tucson actually went up when compared with the night before.
More than half of the Tucson (Carl’s camera) detection are Orionids. In San Diego (Bob’s camera), only ~1/3 of the detections are Orionids. Why the difference? On average the Orionids are brighter than Sporadic meteors. The Tucson camera can only see the brightest meteors so a higher percentage of what it sees are Orionids. The San Diego system can spot much fainter meteors, as a result it does a much better job of detecting the many more fainter Sporadics. Now that the Moon is no longer an issue, the San Diego system will be able to detect even more Sporadics.

TotTime – Total amount of time each camera looked for meteors
TOT – total number of meteors detected
SPO – Sporadics (meteors not affiliated with any particular meteor shower)
NTA – Northern Taurids
STA – Southern Taurids
ORI – Orionids
EGE – Epsilon Gemininds
LMI – Leo Minorids
Below is a movie showing all 64 meteors detected by the Tucson system. See how many you can find. Many of the meteors are barely visible and only appear as short streaks. For reference, only the brightest stars are visible. When the video starts you can make out the Cygnus and Pegasus. By the end of the night, the constellations of Perseus, Auriga and Gemini are most evident.
