[vsnet-alert 3929] Photometry of supernovae 1999go and 1999gp

[Kevin Krisciunas <kevin@lensing.astro.washington.edu>]

In IAU Circulars 7339 and 7340 there is some near infrared photometry
by me of these two supernovae (from Dec 27, 1999 UT).

Here is some preliminary photometry by Kevin Krisciunas with the Apache
Point Observatory 3.5-m telescope and the facility CCD camera SPIcam, from
30 Dec 1999 and 1 Jan 2000 UT.

Given are internal errors.  Realistic uncertainties are +/- 0.02 mag or greater.
