SUPERNOVA 1999fz IN UGC 8164
     T. Puckett, A. Langoussis, and D. George, Mountain Town, GA,
report their discovery of an apparent supernova (mag 15.2) on an
unfiltered CCD frame (limiting mag 20.1) taken with the Puckett
Observatory 0.60-m automated supernova patrol telescope on Nov.
18.40 UT.  SN 1999fz is located at R.A. = 13h02m16s.34, Decl. =
+78o32'29".4 (equinox 2000.0), which is 2".0 west and 1".3 south of
the center of UGC 8164.  SN 1999fz was also present on unfiltered
CCD frames taken on Nov. 21.98, but it does not appear on a Palomar
Sky survey image (limiting mag 20.0) taken on 1952 Oct. 22.

HD 209458
     R. Rebolo, M. R. Zapatero Osorio, H. J. Deeg, and J. Licandro,
Instituto de Astrofisica de Canarias; and J. Marti, University of
Jaen, report: "CCD photometry of the star HD 209458 obtained at the
1.5-m Spanish Telescope at Calar Alto reveals a transit egress of
the planet reported on IAUC 7307, with a depth of 0.023 +/- 0.005
mag, on Nov. 18.87 UT.  Ingress started before observations, but
assuming an orbital period of 3.523 days, the transit lasts 3.0 +/-
0.1 hr.  Best fits give an orbital inclination of 87.0 +/- 0.5 deg
and a planet radius 1.34 +/- 0.07 that of Jupiter."
     R. A. Street, T. A. Lister, A. Cameron, and K. Horne, St.
Andrews University, report that 640-nm narrowband CCD photometry of
HD 209458 with the 0.9-m Gregory telescope in St. Andrews confirms
that a planetary transit with depth of 0.019 +/- 0.003 mag occurred
from Nov. 18.760 +/- 0.021 to 18.903 +/- 0.031 UT.  Z. Ioannou, C.
Hellier, R. D. Jeffries, and T. Naylor, Keele University, report
that V-band photometry with the 0.6-m telescope at Keele
Observatory are consistent with an egress as reported above, but
the increasing airmass makes the data from this time onwards
unreliable.  For further details, see
