EX HYDRAE
Brian Marsden relays a report from F.M.Bateson, Royal Astronomical
Society of New Zealand that this dwarf nova (RA 12h49m43s
DEC -28 58.7, 1950) is having a rare outburst. A.F.A.L.Jones of
Nelson has: Apr. 28.33UT, 10.1; 29.34, 10.6; 28.35, 10.4. The
last outburst was reported in 1987 (IAUC 4383, 4385, 4387).

NOVA IN THE LARGE MAGELLANIC CLOUD 1991
A. C. Gilmore reports the following photometry obtained with the
0.6-m Cassegrain reflector at Mt. John University Observatory on
Apr. 21.39 UT:  V = 10.23 +/- 0.01, U-B = -0.8 +/- 0.2, B-V = 0.00
+/- 0.01, V-R = +0.11 +/- 0.01, V-I = +0.18 +/- 0.03.
W. Liller, Vina del Mar, Chile, notes that this nova is now the
brightest one seen in the LMC; its peak absolute magnitude is ex-
pected to equal approximately that of V1500 Cyg.  Visual magnitude
estimates (those by Liller are photovisual):  Apr. 19.001 UT, 12.5
(Liller); 19.98, 11.8 (Liller); 21.04, 10.4 (Liller); 21.99, 9.8
(Liller); 23.76, 8.8 (T. Cooper, Benoni, R.S.A.); 24.73, 9.2
(Cooper); 24.77, 9.0 (D. Overbeek, Edenvale, R.S.A.).
