24 Aug 2007 | Abstract: | Starting from April 2007, a search for solar daily variation of the muon
intensity ($E_mu >0.2$ GeV) at sea level and using two directional muon
telescopes is in progress. In this survey, several ground level enhancements
(GLEs) on the muon counting rate background have been found. Here, we highlight
one of them, observed in the vertical telescope on 07 August 2007 for the
following reasons: The GLE consists of a single narrow peak, with a statistical
significance of 4.4$sigma$. The GLE is in temporal coincidence with a SWIFT
trigger $N^0287222$, at 21:16:05 UT according to the Burst Alert Telescope
(BAT) on board of the SWIFT spacecraft. However, the Swift StarTracker had lost
stellar lock minutes before that and the resulting improper s/c attitude
information caused BAT to "trigger" on a known source. Even so, the SWIFT
trigger coordinates are inside the effective field of view of the vertical Tupi
muon telescope. The temporal and directional coincidences between this GLE and
the SWIFT satellite unknown event strongly suggest that they may be physically
associated. Details and implications of this possible association are reported
in this work. | Source: | arXiv, 0708.2904 | Services: | Forum | Review | PDF | Favorites |
