SUPERNOVAE 2003aq AND 2003ar
     Further to IAUC 8064, T. Boles reports his discovery of two
apparent supernovae on unfiltered CCD images:

SN      2003 UT      R.A.  (2000.0)  Decl.    Mag.      Offset
2003aq  Feb. 6.070  14 10 07.24  +17 37 05.3  18.5   4".6 E, 8".1 N
2003ar  Feb. 6.162  16 02 08.11  +70 24 55.5  17.9   4".8 E, 5".9 S

Further magnitudes from Boles' images:  SN 2003aq in NGC 5490C,
2002 Apr. 6 UT, [19.0; May 30, [19.5; 2003 Feb. 14.119, 18.0.  SN
2003ar in MCG +12-15-47, 2002 Sept. 7, [19.0; 2003 Jan. 23, [19.5;
Feb. 14.142, 16.8.  SN 2003aq and SN 2003ar are both absent from
second Palomar Sky Survey red and blue plates.


2003 CP_20
     MPEC 2003-C63 contains observations, orbital elements (a =
0.76 AU, e = 0.29, i = 25 deg, H = 16.3), and an ephemeris for an
object, discovered near its maximum possible elongation (76 deg) on
Feb. 11 by LINEAR, that is the first minor planet with a confirmed
aphelion distance < 1 AU (Q = 0.978 AU).  The minimum possible
distance from the earth is currently 0.19 AU (but passages within
0.05 AU of Venus are occurring).


IGR J16318-4848
     N. Schartel, M. Ehle, M. Breitfellner, M. Guainazzi, P.
Rodriguez-Pascual, M. Santos-Lleo, P. Calderon-Riano, P. Munuera-
Gallardo, B. Gonzalez-Garcia, and R. Perez-Martinez, XMM-Newton
Science Operations Centre, report that an XMM-Newton target-of-
opportunity observation on Feb. 10.7 UT shows a bright source at
R.A. = 16h31m48s.6, Decl. = -48o49'00" (equinox 2000.0; uncertainty
about 4") with both EPIC cameras (p-n and MOS) during a 25000-s
exposure.  This position is consistent with that measured for IGR
J16318-4848 by INTEGRAL (IAUC 8063).  The p-n count rate shows
clear evidence for variability covering a range between about 0.2
and 0.75 counts/s.  Images from both EPIC cameras, together with a
light curve and spectrum from the p-n camera, are provided at
http://xmm.vilspa.esa.es/external/xmm_news/items/IGR/index.shtml.
