. Comment on J1640+1220 . Augusto, Wilkinson & Browne (1998) show a 5 GHz MERLIN image and describe the source as a core-jet: their jet component is at PA=-50 . This, and our image, imply a gently curved jet from mas to 100 mas scale. The mas-scale structure is similar in the 8.4 GHz image from the VLBA Calibrators database. VLBApls home page .

About Zones of Resonant Returns of Asteroid Apophis . ... Asteroid Apophis is one of extremely dangerous NEOs. ... Using analytical and numerical tools, we investigate the loss of precision after the Earth approach in 2029 and the possible approach in 2036. ... Possible trajectories of collisions with the Earth have been found analytically and numerically in this chaotic region. To construct these trajectories we used quasi-random intermediate motions, made up from resonant collision orbits. ...

... It is found that the correlation coefficients between these two parameters calculated separately inside and outside the sunspot formation zone ±30 have cyclic variation and occur in anti-phase. This suggests different mechanisms of formation of the corona in the fields of small, medium, and large scales. ... The relationship between the coronal green line brightness (CGLB) and the magnetic field strength (MFS) has been investigated by constructing the corresponding synoptic maps for the 1977-2001. ...
