... Authors: Laurent Loinard 1 2 , Ronald J. Allen 1 We present new interferometric 12 CO(1-0) and single-dish 12 CO(3-2) observations of the central parts of D478, a large (> 200 pc) dark dust cloud located in a quiescent region in the inner disk of M31 where single-dish 12 CO(1-0) and 12 CO(2-1) observations were previously obtained. Only a small fraction (< 15%) of the 12 CO(1-0) flux previously detected in this region with the single-dish telescope is recorded by the interferometer. ...

... a major flood of the entire Upper Mississippi River basin which resulted in very wide spread agricultural and commercial damage. On August 10, an enormous plume of turbid river water was detected extending eastward from the Mississippi River delta region. River water discharged on the western side of the delta flowed eastward around the south side of the delta, joining additional river water discharged from passes on the south and east sides of the delta. ...

... This program was created for correlating chosen regions in the series of fts images. ... Chosen regions' . ... In this section the program counts the integral for each region of the grid for each image. ... As a matter of fact, the integral is total brightness of the region and it is counted by 'int_tabulated' IDL function. ... In addition, the program will show the count of the regions which correlate with the corresponding region (the brighter region means the bigger count) and its contour. ...
