Eric, Jeff and I divided up the task of inspecting the top multiplets. I'm doing those with rank mod 3 = 0. Here are my comments thus far: adjusted, combined spike 0 2407045628 power 132K 16 dec 06 3 same 6 2 high-power spikes 21 jun 08 9 1 of the same 12 same 15 same 18 same 21 2K power signal from 18 mar 10 24 1K power signal from 18 mar 10 27 same 30 2 signals power 55, 6 seconds apart 33 same 36 2 signals power 74, 26 39 2 signals power 26, 83 42 similar 45 2 signals power 44, 6 seconds apart gaussian 0 2 signals, first is drifting RFI 3 2 signals, 2nd is drifting RFI 6 ok 9 2 signals, first is drifting RFI 12 ok 15 2 signals, first is drifting RFI 18 2 signals, first is drifting RFI 21 2 signals, first is drifting RFI 24 2 signals, 2nd is drifting RFI 27 ok 30 3 signals, 2nd is drifting RFI pulse 0 2 signals, 7 sec apart 3 2 signals, 20 sec apart 6 2 signals, 7 sec apart 9 2 signals, 7 sec apart, possible RFI 12 2 signals, 6 sec apart 15 2 signals, 20 sec apart 18 7 signals in same minute; all RFI 21 2 signals, 7 sec apart 24 2 signals, 6 sec apart 27 2 signals, 7 sec apart, possible RFI triplet 0 12 signals from same 3 minutes, all RFI 3 2 signals, 20 sec apart 6 ok 9 2 signals, 15 sec apart 12 2 signals, OK autocorr 0 2 signals, one 35K power 3 2 signals, one 26K power 6 12 signals; OK 9 3 signals, 1, 30 sec apart 12 2 sigs, 1 min apart 15 10 sigs, ok 18 2 sigs, 25 sec apart 21 2 sigs, 13 sec apart 24 2 sigs, 50 sec apart 27 2 sigs, 14 sec apart |

Many of the top scoring 200 pixels are from one of two regions: ~21.5 RA, ~10.1 Dec; or 5.4-5.5 RA, 28.5-29.5 Dec. Any specific reasons for this? Are these directions more likely to be affected by RFI from local RADAR, or known communications satellites? Alternatively, are there any nearby stars within these pixels with planetary systems? ![]() |

I would also like to know. |

The most recent top scoring pixels now focus on a region around 23.66 RA 13.5 Dec. This doesn't correspond with any known geostationary satellite. According to the SDSS sky survey, there is a magnitude 15 star at that position. I'm not reading much into that, since you can find a faint star almost anywhere you care to look. However, for those that want to follow this up the coordinates are: SDSS J013439.49+133008.0 Object ID 1237649918969446408 RA 23.6645527070509 DEC 13.5022256386534 I can't find any other information about it (distance, spectra, etc.) ![]() |
