Arizona is still in the tight grip of the monsoon, however, a fairly
substantial sucker hole appeared in the cloud cover at about 0300 local
time. Spectropolarimetric measurements of four blazars were made
before more clouds ended this very short night near the start of morning
twilight. The seeing varied between 1.2-3.5 arcsec. For those keeping
score: Monsoon 4 - Observer 2.
