Abstract (from CDS):

We report two new radio transients at high Galactic latitude, WJN J0951+3300 (α = 09h51m22s±10s, δ = 33°00'±0°.4, b = 50°54'.2) and WJN J1039+3300 (α = 10h39m26s±10s, δ = 33°00' ± 0°.4, b = 60°58'.5), which were detected by interferometric drift-scan observations at 1.4 GHz at the Waseda Nasu Pulsar Observatory. WJN J0951+3300 was detected at 16:49:32 UT on 2006 January 12 with the flux density of approximately 1760.5±265.9 mJy, and WJN J1039+3300 was detected at 17:13:32 UT on 2006 January 18 with the flux density of approximately 2242.5±228.7 mJy. Both of them lasted for a short duration (≤2 days). The possibility that the distribution of the WJN radio transients is isotropic was suggested in a previous study. Having re-evaluated the log N-log S relation with the addition of the two new objects reported in this paper, we find that the slope is consistent with a slope of -1.5 and the previous result. Additionally, although there are several counterparts to WJN radio transients, we found that one of the quasar counterparts within the positional error of WJN J0951+3300 could be a radio-loud quasar. We have discussed whether or not WJN J0951+3300 could be of this quasar origin.
