| Abstract |
In continuing follow-up observations of the millisecond pulsar IGR J17511-3057 (ATEL #2197), the pulsations from this source have become difficult to detect. On date 2009-10-08 UT, RXTE PCA serendipitously detected 435 Hz X-ray pulsations, identified as the nearby pulsar XTE J1751-305, which is in the same field of view. This is consistent with the recent INTEGRAL report (ATEL #2235). In a pointed RXTE PCA observation on 2009-10-09 at 04:00 UT, pulsations at 435 Hz were only weakly detected.
