\IBVSOobj{
 NSV 14773 = HD 224355 = HIP 118077 }
{
Hipparcos data (Perryman et al., 1997) confirm that NSV 14773 is an 
EA-type eclipsing binary with the elements: HJDminI = 2449040.829 + 
12.1564 d X E. V-magnitude range (Otero, 2003) is 5.57 to at least 
5.68. This is probably an eccentric system with a secondary eclipse at 
phase 0.67. The 5th edition of the Bright Star Catalogue (Hoffleit and 
Warren Jr., 1991) gives F1/6V+F3V as spectral types and 12.156153 days 
as the spectroscopic period. The NSV Catalog (Kukarkin and Kholopov, 
1982) lists it as a suspected eclipsing binary with an amplitude of only 
0.05 mag.

{
The star was considered irregular (Ahnert, 1951)
and red (spectral type M5, Neckel, 1958).
In an e-mail message from Skiff (2004), it was noted
that the spectral type referred to a neighbor, GSC 01320-01109, whereas it was
V337 Ori (GSC 01320-00167) that actually varied according to ASAS3 data. This
finding agrees with that of G. Richter (1965)
that the star was white. Our analysis of the ASAS3 and ROTSE1/NSVS data
shows that the star is a high-amplitude Delta Scuti variable with the light
elements: Max = 2453068.586 + 0.201261 d x E, range 10.90 - 11.45 (V),
M-m = 0.35 P (ASAS3), range 11.2 - 11.6 (ROTSE1).

SZ Lib is currently listed in the GCVS as type EB: with a period of 6.65

star with the following elements: JDmax = 2451275.295 + 0.540286(15) d X E, 
range 14.0 - 14.8 (R). This conclusion is also supported by ASAS 
data, but with a period of 0.540313(5)d. The incorrect GCVS period is 
probably an aliasing artifact.

PQ Her was considered by Akerlof et al. (2000) to be a
Cepheid with P = 4.54563093 d. From the NSVS data, we prefer the star's
classification as an RS CVn star without eclipses, with the elements:
JDmax = 2451401.81 + 4.5739 d xE, range 12.4 - 12.6 (R). This classification
is in a better agreement with the spectral type (G8, Bond, 1978)
for the given period, with the star's relatively small amplitude,
and our suggested identification with the X-ray source 1RXS J180732.1+401531.

{
GSC 02102-01349 lies in the field of AU Her and was originally identified
as a variable by Brown \& Benson (1997). It is given as an LPV in the
ROTSE-1 list of new variables (Akerlof et al. 2000). Further analysis of
the ROTSE-1 data shows that it is a complex small-amplitude red variable
(SARV) with at least two frequencies. These are 0.0320 and 0.0280
cycles/day corresponding to periods of 30.9 and 35.7 days. The closeness
of the periods produces an amplitude modulation but there is also other
activity. The 2MASS colours of J-H=0.88 and H-K=0.23 suggest that this is a
very cool object.

ROTSE1 gives position in between GSC 3101-0683 and GSC 3101-1186 and the 
catalogue entry is obviously a blend of these two stars. CCD observations 
revealed that the true variable star is GSC 3101-0683. Other information given 
in ROTSE1 catalogue, especially variability type (EW) and period 
(0.31630(6) days) remain likely valid. Clearly, the amplitude is higher, at

V1898 Cyg

{
V1898 Cygni was identified as a spectroscopic binary by Abt et al. (1972), who
proposed a period of 2.9258 days.
The system was then studied by Halbedel (1985), who established the eclipsing
nature and concluded that it had a period of 3.0239 days, with similar depth
primary and secondary eclipses.
We observed V1898 Cygni at Appalachian State University's Dark Sky Observatory.
Observations obtained on JD 2452169 revealed a previously undiscovered secondary
eclipse, meaning the true period is about half that proposed by Abt or by
Halbedel.

A linear regression analysis of minima resulted in a new period of
1.5131273 days (+/- 0.0000006 days). The secondary may be slightly
displaced to earlier than phase 0.5 but asymmetries in the eclipses make this
uncertain.
    Our original choice of comparison star, HD 200830, 
was revealed to be variable. On the night of JD 2452143 it was found
to be about 0.2 magnitudes fainter in the V than usual, and it showed variations
on other nights as well. It is listed in the literature as having H-alpha
emission.

Hiller et al. (2004) for their 1991 data. AM Leo has a close visual companion 
and most measures included the companion's light, but a few excluded it. The 
1983 B and V light curves agree well those of Hiller et al. (2004) but the 
U magnitudes are systematically 0.13 mag fainter.

In the course of maintaining the database Eclipsing Binaries O-C Files for the
AAVSO (Nelson, 2005a), the author found a number of periods that did not
give a rational fit for the existing published periods. Random deviations --
sometimes as large as 0.1 days -- could not be plausibly explained by observer
error. For nine such stars, inserting the existing times of minima (ToM) into
software `ToMcat' led to the discovery of new periods giving much better O-C
relations. (This software, which uses a modified Fourier transform, is
available at the author's website -- see Nelson, 2005b.) The remaining star,
V1157 Aql, had too few points for ToMcat; Excel solver was used instead.
These new periods and other information, are given in the accompanying table.
The O-C plots (in Excel format) may be examined on the AAVSO database (Nelson
2005a), or by request from the author.

ASAS J002511+1217.2 was identified as a WZ Sge-type dwarf nova by Golovin et al.
(2005) after a first-ever observed outburst in September, 2004. A search of the
Harvard College Observatory Photographic Plate Collection was undertaken, and 
one additional outburst discovered from September, 1938:

Temporally adjacent plates taken 19 days before and 22 days after this outburst show no sign of the star to the plate limit.

While trying to find a time of minimum light of the little observed 
eclipsing binary AS And we got aware of the fact that the elements of variation
given in the GCVS do not represent our CCD observations. During 30 nights 
between JD 2452500 and JD 2453674 we obtained a total of 291 CCD observations 
using the 35cm RC reflecting telescope of R. Szafraniec observatory, 
Switzerland. The data up to JD 2453324 were collected with a SBIG ST-6 camera 
without filter, while starting with that date a SBIG ST-10 camera and a V-filter
were used. The corrected elements of variation are found to be:
\\
JD(hel,min) = 2452548.5944 + 2.42063 * E.
\\
The range of variation is 12.65 - 14.10 (12.80)  R-mag.

Automated sky surveys have led to many newly discovered variable stars

Bernhard (2003). Bl\"attler has performed unfiltered CCD 
observations with a SBIG ST-7 camera attached to his 0.15-m Starfire refractor

326 measurements were obtained, using GSC 1830-2063 (10.78 mag) as comparison 
and GSC 1830-1729 (11.67 mag) as check star. A linear regression of his 20 times
of minimum with the ROTSE1 data as well as minima reported in IBVS No. 5599 and 
IBVS No. 5643 yields the following results: Type: EW (RRc?); JD(min I, hel) =

{
The Wolf-Rayet star WR 143 (HD 195177) was assumed to be binary since its first 
classification as WC5+(OB) (Smith, 1968). Recent spectroscopic and photometric 
observations strengthened this assumption (Varricatt \& Ashok, 2006). The NSVS 
light curve of WR 143 clearly shows its ellipsoidal or eclipsing binary nature. 
The figure shows the phased NSVS light curve according to the following elements:
\\
$$T_min[HJD] = 2451187.5 + 139 \times E$$
\\
The significant noise superimposed on the light curve, originated from the 
erratic flux of the Wolf-Rayet star and that of the Be companion, does not 
allow us to decide wether the binary is ellipsoidal or eclipsing type.
