From: TerryMosel aol.com Date: Sat, 12 Jun 2004 19:59:21 EDT Subject: Delta Sco IS bright! Hi all, I got a much better brightness estimate later tonight, when Delta Sco Spica were about the same altitude above the horizon. ... At 00.50 (23.50 UT on 12 June) I estimated that Delta Sco was only 0m.4 fainter than Spica, making it 1m.4, or 0m.9 brighter than its quoted magnitude of 2m.3. ... Clear Skies, Terry Moseley .

... An estimate the rotation period of cometary nuclei is important for understanding and describing the physical processes of the cometary activity. Unfortunately, the measurements of the rotation periods of the comet nucleus depend on the model assumptions and it is one of the main reasons for the scatter of the estimates given in various articles for a given comet. ... Right: the image of the comet 29P/Schwassmann-Wachmann 1 obtained at the 6-m telescope. ...

... The procedure of radiometer signal integration can be considered as a sort of reducing dimension of the initial sampling space, where the samples are the result of analog-to-digital conversion. ... The probability distribution of the signal and spikes is completely known. ... The quality of the considered algorithm could be also illustrated by Figure 2 . ... One could see the considered adaptive algorithm is preferable even by low degree of compression, because all spikes have been depressed. ...
