                ------------- ACTIVITY LOG --------------
 Observing Specialist: W. Ketzeback
 Beautiful photometric night for the Summer Solstice. Good seeing until
 about 0400 when it varied widely and was affecting guiding.
 Had some difficulty mounting DIS this evening (PR2003103) and mirror covers
 closing in automatic mode (PR2003104) this morning. The echelle guider
 crashed once tonight about 0350. No PR filed and I could not find the number
 for an open PR on this but I emailed several interested parties.
