Anomalous X-Ray Pulsar AXP 1E1547.0-5408 Disrupts Earth .
Starting around January 21st
A simultaneous observation of lower energy X-rays by the Swift satellite indicates that the X-ray emission is travelling towards us through dusty regions of our Galaxy causing ring-like halos in the X-ray images (GCN 8848). This allows scientists now not only to study the neutron star itself, but also the interstellar medium of the Milky Way.
there have been 13 additional triggers of Fermi GBM from this source. The GBM on-board locations are all consistent with the AXP 1E1547.0-5408 position. So there are a total of 31 triggered bursts from this source. Many other bursts were recorded during times where GBM was still in trigger mode.

Konus-Wind have seen 11 triggers from this source. The first trigger at 2009-01-22 T0=3554.882 s UT (00:59:14.882) contains many bursts and represent the cluster of bursts which started at ~T0-210s. The second trigger also contains several bursts. Remaining triggers contain single bright bursts. There is a data gap from 02:13 to 15:43 UT on Jan 22, 2009 which cannot be recovered. The following is a list of the Konus-Wind triggers with preliminary estimations of the bursts fluences and peak fluxes. The KW trigger times and corresponding Earth-crossing times are given. ------------------------------------------------------------------- # Date T0(KW) T0Earth Localized Fl** PF** UT UT by ------------------------------------------------------------------- 1* 20090122 00:59:14.882 00:59:18.550 GBM 8.0 8.0 2* 20090122 02:09:22.183 02:09:25.849 BAT 5.7 1.3 3 20090122 17:02:52.833 17:02:56.474 BAT 2.7 2.5 4 20090122 21:07:56.190 21:07:59.824 - 1.0 3.4 5 20090122 23:14:50.460 23:14:54.090 GBM 4.7 7.8 6 20090123 01:19:37.838 01:19:41.465 BAT,GBM 2.7 7.5 7 20090123 02:42:05.150 02:42:08.774 GBM 3.2 9.7 8 20090123 16:54:33.488 16:54:37.087 GBM 1.3 5.6 9 20090125 08:43:37.781 08:43:41.303 IBIS 250 300 10 20090125 23:00:32.802 23:00:36.294 IPN,GBM 7.6 19 11 20090126 04:48:01.917 04:48:05.397 GBM 1.6 5.7 ------------------------------------------------------------------ * - these triggers contain several bursts, in Table we give total fluence of all bursts and peak flux of the brightest burst ** - Fluence (20-200 keV) in units of 1e-6 erg/cm2 *** - Peak Flux (20-200 keV) on 4ms time scale in units of 1e-5 erg/cm2/s Some Abbreviations: BAT: Swift BAT GBM: Fermi GBM IBIS: Imager on Board the INTEGRAL Satellite
We observe 30 significant signatures out of which 9 were not reported by others and these events mostly took pace in late 21st January, 2009 (UT) before other satellite results were reported. However, the timings of the remaining 21 events match with the satellite observations. A list and the light curves of all the major events seen by us in the 22nd January (IST) can be found in http://www.bose.res.in/~chakraba/axpsgr.html. Since both the amplifications and the attenuations were seen, often one after the other, each event could tell us about the energy spectrum in each burst as the upper ionosphere would be primarily affected by soft-X-rays and the lower ionosphere would be primarily affected by the hard-X-rays.

Uh, that's not a gravity wave.
