V1333 AQUILAE
A. M. Levine, Massachusetts Institute of Technology (MIT), and
B. Thomas, Goddard Space Flight Center (GSFC), on behalf on the
RXTE ASM team at GSFC and MIT; M. Garcia and P. Berlind,
Smithsonian Astrophysical Observatory; and P. Callanan, University
College Cork, report that the low-mass x-ray binary Aquila X-1 (=
V1333 Aql) appears to be in a moderate-intensity outburst in quick-
look results from the RXTE All Sky Monitor. Recent daily-average
flux levels in the band 2-12 keV are as follows: Jan. 27, about 60
mCrab; 28, 120; 29, 190; 30, 260; Feb. 1, 310; 2-5, about 360.
Observations of the optical counterpart V1333 Aql from the Whipple
Observatory 1.2-m telescope on Feb. 6.543 UT yield V = 16.9.
Observations at other wavelengths are encouraged.
