				AAVSO ALERT NOTICE 199 (February 9,1995)

1900-01 POSSIBLE NOVA IN AQUILA

We have been informed by the Central Bureau for Astronomical Telegrams (IAU Circular 
6133) of the photographic discovery of a possible nova in Aquila by Kesao Takamizawa, 
Saku-machi, Nagano-ken, Japan, at photographic magnitude 8.1, and reported by S. 
Nakano, Sumoto, Japan. The discovery was made on two films taken on February 7.839 
and 7.842 UT, using T-Max 400 film and a 10-cm f/4.0 lens. No corresponding image 
appeared down to magnitude 12-14 on photographs taken on May 12, June 14, or October 
23, 1994. A precise (2000) position has been provided by Y. Kushida, Yatsugatake South 
Base Observatory, Japan:

		RA = 	19h 05m 26.57s	Dec. = 	-01deg 42'03.5"	(2000)
			19h 02m 51s		-01deg 46'40"	(1950)

Estimates of this object, which has not been confirmed as a nova, include: Feb. 7.839 UT, 
8.1 (Takamizawa); 8.854, 8.4 (Takamizawa); 8.873, 7.5: (Kushida); 9.435, 8.2 (C. Scovil, 
Stamford, CT); 9.531, 8.5, reddish color (P. Collins, Scottsdale, AZ).

Accompanying is a chart from the AAYSO Variable Star Atlas showing the location of the 
object. Observers are requested to use this chart to observe the star, and to report 
observations to AAVSO Headquarters by telephone, fax, or email so we may inform the 
astronomical community. Please be sure to specify which comparison stars you have used 
in making your estimates - this is very important, as there are many comparison stars 
present on this section of the Atlas.

Congratulations to Kesao Takamizawa on his discovery!

REQUEST TO MONITOR DWARF NOVAE

We have received a request from an astronomer at Keele University, England, for our 
assistance in monitoring the dwarf novae below between now and February 20. We are 
informing him daily of the status and brightness of the target stars:

0103+57 HT Cas	0749+22 U Gem	1109-37 V436 Cen
0130+50 KT Per	0814+73 Z Cam	1640+25 AH Her
0547-05 CN Ori	0855+18 SY Cnc	1934+30 EM Cyg

Please monitor these stars every night you can and report your observations, even if the 
stars are at minimum, daily to AAVSO Headquarters by noon EST (1700 GMT). 
Accompanying is a chart from the Royal Astronomical Society of New Zealand for V436 
Cen. If you need charts for anyof the other stars on this list, please contact Headquarters.

1436-63 N CIR 95

A precise (2000) position for N Cir 95, discovered by W. Liller, Vina del Mar, Chile (see 
AAVSO Alert Notice 198), was obtained by A. Gilmore and P. Kilmartin using the Mt. John 
University Observatory, New Zealand, 0.15-m f/15 astrograph:

RA = 	14h 44m 53.48s	Dec. = 	-63deg 53'55.6"	(2000)
	14h 40m 51s		-63deg 41' 17"	(1950)

N Cir 95 continues to be bright, as indicated by the following observations:

Jan 29.451, 7.90 V (Gilmore); 29.519, 7.89 V (Gilmore); 29.525, 7.89 V (Gilmore); 29.531, 
7.89 V (Gilmore); 29537, 7.89 V (Gilmore); 30.14, 7.47 CCDV (Liller, via IAU Circular 
6131); 31.474 UT, 7.6 (B. Sumner, Melbourne, Australia); 31.8, 7.2 (Y. Fernandez, 
Montevideo, Uruguay, via IAU Circular 6131); 31.998, 8.4 (D. Overbeek, Edenvale, S. 
Africa); Feb 1.063, 8.1 (Overbeek); 1.934, 8.6 (T. Cooper, Benoni, S. Africa, via J. Hers); 
2.63, 8.26 V (Gilmore); 3.853, 8.9 (L. A. G. Monard, Pretoria, S. Africa); 4.951, 8.8 
(Monard); 8.607, 8.76 V (P. Kilmartin, Mt. John University Observatory, New Zealand).

Please continue to observe this nova using the chart distributed with AAVSO Alert Notice 
198 and report your observations to AAVSO Headquarters.

REMINDER TO MONITOR CATACLYSMIC VARIABLES AND HIPPARCOS RED 
VARIABLES

Please remember the requests made in AAVSO Alert Notices 196 and 197 to monitor, 
respectively, some Hipparcos red variables for photometric calibration (through February), 
and some cataclysmic variables for the Astro-2, EUVE, Voyager, and ASCA satellites 
(February 13-March 17). See these Alert Notices for details and the lists of target stars, 
and request any charts you may need for these stars from Headquarters. Your 
participation in these projects is crucial to their success!

Observers are welcome to use the charge-free number (800-642-3883) to report 
observations. The answering machine is on nights and weekends for your convenience.

Janet Mattei, who is still in South Africa attending a conference and giving several talks, 
and I thank you for your efforts and your valuable astronomical contributions.

Good observing!

Elizabeth O. Waagen 
Senior Technical Assistant
