OH/IR stars as the progenitors of planetary nebulae P. te Lintel Hekkert and A.A. Zijlstra Based on a new sample of (IRAS based) OH/IR stars, and the catalogue of planetary nebulae compiled by Acker (1983), we study the relation between these two groups of objects, in terms of the kinematics and the Galactic distribution. ...

SN 1989B Light Curve Analysis. ... In the light curve depicting their observations, definite trends are noted, here is a "thumb-nail" analysis of the the magnitude estimations of the bright SN (1989B) in the galaxy NGC 3627 (M66). ... The observations were inserted against the V magnitude templete of BL, CCD photometric data, (Wells et. al, (1994) and a color trend (B-V) histogram of the mean type Ia SN (BL)(nutemp.gif). Key Words: Amateur Observations, Supernova, Magnitude Estimates, 1989B . ...

... Old World First Asteroid Radar Echo. ... It testifies that 4179 Toutatis is a double object like asteroid 4769 Castalia. ... Interference of Radar Echo from the Binary Asteroid 4179 Toutatis. ... An analysis of the 6-cm radar data revealed quasi-harmonic oscillation of the echo’s “central” Doppler frequency with a period of about 14 sec and a deviation of about (0.7*B) Hz, where B is the echo bandwidth, which for 4179 Toutatis was equal to 2.1 Hz and 1.9 Hz for 1992 Dec 8 and 9, respectively. ...

... Figure 1a illustrates the summary diagram (2 log L, log S ) based on the field intensity contour lines for 7 active regions plotted at 200 G steps in the range of 2200­400 G. One can see that the relationship under discussion is well represented by two straight lines, one corresponding to the log S range from 2 to 7.2 and another, from 7.2 to 9. ... Then, we plotted 2 log L versus log S for all field lines of a given intensity, no matter which sunspot or sunspot group they belonged to. ...
