We have detected three strong optical transient in the Palomar-Quest (PQ) survey
drift scans obtained at the Palomar 48-inch Samuel Oschin Telescope on 19/20/21 July 2007
UT. The transients are unresolved, and at the following J2000 coordinates:
PQT070719:151221+123004 19Jul07 UT: 05:58:52 RA: 15:12:21.38 Dec: +12:30:04.0
PQT070721:221303-043900 21Jul07 UT: 08:21:22 RA: 22:13:03.91 Dec: -04:39:00.3
PQT070721:231237-051343 21Jul07 UT: 09:20:03 RA: 23:12:37.23 Dec: -05:13:43.7

None of the three sources are present in the previous PQ images (reaching
down to ~ 21 - 22 mag), the archival SDSS or DSS images, in NED, or the FIRST
and NVSS radio surveys.
PQT070719:151221+123004 was present in both scans of the 19th.
PQT070721:221303-043900 was present n the scans on the 19th and the 21st.
PQT070721:231237-051343 is close to a galaxy and has only one scan (three images
separated by ~3 minutes each). While no proper motion is seen in these images,
a slow moving asteroid can not be ruled out.
All sources were detected and published as VOEvents in near-realtime at
.
Further observations, especially spectroscopy, are strongly encouraged.
