The English question8 says that the smaller component is fainter. The Russian/Bulgarian proceedings use the stronger approximation that it is dark. The English wording is retained. The exact observing night is not dated on the supplied practical sheet.

Условие

Write the observational program for this night on a 40-cm telescope. What stars would you observe this night? Write sequence of the observations.

Stars to observe:

	Star	$V$ (mag)	$\alpha$	$\delta$ (1950)
1	$\eta$ Aql	$3.5$	$19^{\mathrm h}49.9^{\mathrm m}$	$0^\circ53'$
2	$\beta$ Per	$2.1$	$3^{\mathrm h}04.9^{\mathrm m}$	$40^\circ46'$
3	$\chi$ Cyg	$14.2$	$19^{\mathrm h}48.6^{\mathrm m}$	$32^\circ47'$
4	R Aqr	$12.4$	$23^{\mathrm h}41.2^{\mathrm m}$	$-15^\circ34'$
5	$\alpha$ Ori	$1.3$	$5^{\mathrm h}52.4^{\mathrm m}$	$7^\circ24'$
6	RW Vir	$6.7$	$12^{\mathrm h}04.7^{\mathrm m}$	$-6^\circ29'$

Moon rise: 21:17:26, phase 0.77.

Sideral time for $0^{\mathrm h}$ : $s_0=0{:}31{:}04$ .

You may use all observational time (since $20^{\mathrm h}$ till $5^{\mathrm h}30\,\mathrm{min}$ ).

Local time $\mathrm{LT}=\mathrm{UT}+3$ .

Coordinates of observatory $\lambda=2^{\mathrm h}16^{\mathrm m}$ , $\varphi=44^\circ43'$ .

Put your result into the table:

Star	Interval of observation

Stars that could not be included in the program:
