RELATIVE SUNSPOT NUMBERS Description of Data from SGD Explanation of Data Reports: Relative Sunspot Numbers -- The relative sunspot number is an index of the activity of the entire visible disk of the Sun. ... The provisional daily Zurich relative sunspot numbers, Rz, were based upon observations made at Zurich and its two branch stations in Arosa and Locarno and communicated by M. Waldmeier of the Swiss Federal Observatory. ... This indicates the uncertainty above and below the predicted number. ...

... The numbers of three types of compact binaries containing accreting NSs and BHs, which are most interesting from the point of view of their observational appearances, have been calculated as a function of time: i) X-ray transient source containing a NS in an eccentric orbit around a main sequence Be-star (the observed prototype: A0535+26), ii) BH The evolution of the selected types of X-ray binaries during the first 10 million years after the starburst onset is presented in Fig. ...

Technical Instrument Report WFPC2 97-04 VISFLAT Channel Monitoring M. Stiavelli February 18, 1998 ABSTRACT The whole data set of VISFLAT exposures in F555W is re-analysed and found to confirm the continuing degradation of the VISFLAT lamp. The new data indicate that the lamp degradation is perhaps more a function of cumulative lamp on-time than number of lamp cycles. ... 2 Figure 1: Relative intensity for the four WFPC2 cameras as a function of the cumulative number of lamp cycles. ...

For ``in-band'' frequency switching, the line under investigation is always in the observing band. ... Position Switching or ``Out-of-Band'' Frequency Switching: Here the line is only observed for one half of the time, with noise being present all of the time. ...

... The main periodicity in the Sun 's activity is the 11-year cycle called the solar cycle. ... During the cycle, changes occur in the Sun's internal magnetic field and in the surface disturbance level. ... At the beginning of a cycle the solar magnetic field resembles a dipole which axis is aligned with Sun's rotation axis. ... The sunspot number - and Sun's activity - is at maximum in the middle of a cycle, when the Sun's internal magnetic field is most chaotic. ... Space Physics Text Book of Oulu ...

... The Sun has come all of one day away from breaking its record for the longest period of inactivity for the last decade - reaching a mid-summer low and falling into yet another state of "hibernation". Yesterday, on the first day of autumn, new sunspots appeared on the surface of the Sun following an absence of almost 50 days. ... The first low lasted 51 days, from 21 July until 11 September last year. ... Now, almost a year later, it seems the Sun has hit a new low almost as "deep" as the first. ...

... Summarizing the results of the Hamburg/SAO survey presented in Papers I through V, we discovered altogether from the 1-st priority candidates 433 new emission-line objects (25 of them are QSOs), and for 85 known ELGs we got quantitative data for their emission lines. ... To estimate the total number of BCGs in the HSS zone we should count new BCGs expected from the remaining candidates and those selected in the HSS, but not observed by us since they already were known from other surveys. ...

... This year SSAU provides 1429 state-funded places for admission in all kinds and directions of educational programs. ... In addition, SSAU Admission Committee notes the substantial increase in interest from the foreign applicants this year. The number of applications from foreign countries has already surpassed last year's totals - 76 applications. Based on the experience of admission campaigns of previous years, SSAU expects summer 2014 to enrol about 150 foreign students in the university. ...

... GCR and SCR are primary cosmic rays. 10-15 years after the discovery of cosmic radiation (1919) there emerged two main avenues of investigation in the physics of cosmic rays (CR): 1) nuclear - elucidation of the origin of elementary particles and nuclear interactions; and 2) astrophysical (space physics) - solution of the problem related to the origin and variations (changes in intensity) of CR. ... Besides, the CR flux in interplanetary space is, strictly speaking, not isotropic. ...

... Let us first find out which way -- rise in spectral resolution with some loss in the S/N ratio or increase in the S/N ratio with a fixed spectral resolution -- is better for the purpose of reduction of equivalent width determination errors. ... N -- number of counts for 1 ? ... line equivalent width, . ... Thus if the spectral resolution is managed to be increased (i.e. to decrease )without loss in the number of counts falling at 1 ?, the equivalent width measurement error is then proportional to . ...
