Expected RFI from GPS at 1381.5 MHz
We have just received the following notices from Daniel J. Mertely of NRAO-Socorro that we should be seeing RFI at 1381+/- 2.5 MHz on the dates and times listed below. Extragalactic HI projects that plan to observe around z~0.03 may be affected. Galactic HI projects, or extragalactic projects with either much smaller (< 0.02, say) or larger redshifts (> 0.04) should be OK.
