X-RAY NOVA IN SCORPIUS
B. A. Harmon, S. N. Zhang, G. J. Fishman, C. A. Wilson, W. S.
Paciesas, and B. C. Rubin, report for the Compton Gamma Ray
Observatory BATSE Team: "This object (GRO J1655-40) has become
detectable again, varying between 150-250 mCrab in the band 20-100
keV since Jan. 12. The previous hard x-ray outburst (IAUC 6101,
6106) ended in late December 1994. Emission is seen to at least
200 keV."
SATURN
J. Lecacheux, Observatoire de Meudon; and A. Sanchez-Lavega,
Bilbao University, report: "From CCD imaging of Saturn on 1994
Nov. 22.8 and Dec. 16.8-17.8 UT with the Pic du Midi 1-m telescope,
we derive a drift rate of +9.9 deg/day in longitude (system I) for
the bright yellowish equatorial disturbance observed by the Hubble
Space Telescope on Dec. 1 (confirming our previous report, IAUC
6079). We have also recorded another major bright feature, 135 deg
eastward, with similar latitude and motion; the wind velocity
appears slower by 100 m/s than normally expected at this latitude."
CATALOGUE OF COMETARY ORBITS 1995
A new edition of the Catalogue of Cometary Orbits, complete
through the end of 1994, is now available. It utilizes the new
system of cometary designations and includes detailed cross-
references between this system and the old system (both year/letter
and year/Roman numeral). Other changes from the previous editions
are that the general catalogue lists the single-apparition and
multiple-apparition (i.e., numbered) comets separately (the latter
chronologically by comet number), and that all the information
(including the literature reference) about a particular orbit is
placed on a single line spanning two facing pages. Separate
entries are given for individual components of several split comets,
yielding a total of 1472 entries for 1444 cometary apparitions
referring to 878 different comets, 184 of them of short period. As
an entirely new feature, there is a special tabulation giving
osculating elements for the 116 numbered comets (except for five
that are lost) for the epochs 1995 Mar. 24 and Oct. 10. The 108-
page Catalogue sells for $20.00 ($30.00 for airmail delivery
outside North America). There are also diskette and e-mail
editions with the basic orbital information, and these cost $110.00
($120.00 by airmail) and $50.00, respectively.
