. In an effort to provide a centralized database for indexing locations and descriptions of Shuttle debris, the editors of Astronomy Net have generated a database and web page where reports can be logged. This may or may not prove useful for cataloging debris reports, but Astronomy Net is happy to dedicate computer resources to help out any way possible. We express our sympathy and prayers to the families and friends of the Columbia crew. If you have located Shuttle debris, report it here.
... This applet generates an observing list based on an observer's location and time. ... To use this program, enter in your location, and the local times at which you wish to begin and end observing. The date you enter should correspond to the calendar day at the time at which you begin observing. For example, if you wish to observe from 9:37 PM October 23, 2007 until 3:21 AM October 24, 2007, you would enter 21:37 for the starting time, 03:21 for the finish time, and 10/23/2007 for the date. ...

From Turkic "nart sane" is translated as "bogatyr's water". Old Caucasian legend says that a long time ago there was a pillar by the spring with words on it: "Stranger, stand and bow. The water gives a strength to young, returns health to elder and beauty and love to women." .
... According to standard phase screen theory large values of the intensity indices correspond to focusing conditions. ... It has been found that focusing effects always occur in the multibeam reflection (glint interference) regime. ... Figure 1 . ... First of all, calculations show that multibeam regime arises under slightly larger values of (see the Table 1 ). ... Thus, in our case (reflection from the E layer, altitude about 100 km) focusing is quite possible already when multibeam regime arises. ...
