Meteor activity kicks into high gear in August as seen from the northern hemisphere. The main reason for all this activity is the Perseid shower that peaks on August 13th. This shower is active most of the month and remains above the level of the sporadic background for a week centered on August 13th. The sporadic activity is also near maximum as seen from the northern hemisphere and is now more than double the rates from just three months ago. As seen from southern hemisphere, meteor rates are still decent but falling rapidly. The sporadic rates continue their downward slide and the Perseid radiant does not rise high into the sky as seen in the southern hemisphere. So rates for the Perseids are greatly reduced when compared tobase member includes latching means mounted to the moveable member. One may move the latching means between a first, latching position in which the latching means engages a stop portion of the base member and a second, releasing position. An actuator mounted to the moveable member engages the latching means and allows an operator to drive the latching means between the first and second positions. At least one spring biases the latching means towards the first position. In one embodiment, the latching means includes a plate with a flange portion. In another embodiment the latching means includes a pivoting segment that the actuator engages, an engaging segment that engages the stop portion and a linkage segment that connects the pivoting segment with the engaging segment.
