PERIODIC COMET SCHWASSMANN-WACHMANN 2 (1986h)
J. Gibson reports his recovery of this comet with the 1.5-m
reflector + CCD at Palomar as follows:
1986 UT R.A. (1950.0) Decl. m1
June 26.45597 1 43 45.18 + 7 20 51.4 20
26.47181 1 43 46.07 + 7 20 54.8
27.45764 1 44 41.90 + 7 25 17.5
27.46931 1 44 42.54 + 7 25 20.5
The position is in close agreement with the orbital elements on
MPC 10521, from which the following ephemeris is obtained:
1986 ET R.A. (1950.0) Decl. p r m1
July 9 1 55.13 + 8 12.2 3.468 3.376 20.1

NEW EXTRAGALACTIC OH MEGAMASERS

Martin, Observatoire de Paris, Meudon; M. Dennefeld, Institut
d'Astrophysique, Paris; and G. Paturel, Observatoire de Lyon,
telex: "New, strong, extragalactic OH megamasers have been
discovered with the Nancay radio telescope in the three IRAS sources
11010+4107 (= Arp 148), 15107+0724 and 20550+1656 (= II Zw 96).
The isotropic luminosities at 1667 MHz are 102, 11 and 184 LO,
respectively (adopting H = 75 km s**-1 Mpc**-1). The H I (21 cm) line
has been detected in emission in Arp 148 and II Zw 96 and in
absorption in IRAS 15107+0724. An H I emission line with an
absorption feature has also been observed in the recently-discovered
megamaser III Zw 35 (IAUC 4180)."
