The nova V339 Del (formerly dubbed Del 2013; CBET #3628, IAUC # 9258 ) was detected at radio and
millimeter wavelengths on UT 2013 Sep 08.1 with the VLA and CARMA. Measured flux densities are:
| Freq |
Flux |
Facility |
| (GHz) |
(mJy) |
|
| 28.2 |
0.21 +/- 0.03 |
VLA |
| 36.5 |
0.32 +/- 0.03 |
VLA |
| 95.7 |
3.58 +/- 0.68 |
CARMA |
The flux density rises steeply with frequency, consistent with optically thick thermal or
self-absorbed synchrotron emission.
V339 Del remains undetected at lower frequencies with the VLA; the most recent 3 σ upper limits
from 2013 Sep 05.1 yield <0.33 mJy at 1.4 GHz, <0.12 mJy at 4.7 GHz, and <0.07 mJy at 7.4
GHz.
Radio and millimeter monitoring of V339 Del is ongoing, and we strongly encourage observations
at all other wavelengths.
