2007 Video Observations Table

The table below lists, in reverse chronological order, the video meteor observations obtained by the American Meteor Society during 2007. While most of the abbreviations are clear, several may need clarifying: PST = Pacific Standard Time. PDT = Pacific Daylight Time. TeFF indicates the percentage of an hour spent observing (1.00 = 1.00 hour, 0.50 = .50 hour or 30 minutes). SOL. LG. is the solar longitude of the mid-point of each period. This is used as precise time measurements independent of any time or date. F is the obscuration factor (usually clouds, trees, or hills) where 1.00 = no obscuration and 2.00 = 50% obscuration. SPO = Sporadic (random activity). ANT = Antihelion activity. SHR = Shower activity. Numeric figures under Moon indicate the presence of moonlight and the percentage of the illuminated portion of the moons disk. 1.00 = Full Moon, "+" indicates waxing (before full moon) phase and "-" indicates waning (after full moon) phase. While all other times in this website are listed in universal time (UTC), I chose to list the video data this year in local time since it is obtained from only one source. Please note that between August 15 and October 31 the video system was down due to computer problems. Aurigid data was stored on video tape but the Orionids were clouded out.
