Jakischa. VCLOCK okay. Clear skies at HN, NL, FD, KP, OV, BR, & MK. Partly cloudy at SC & LA. 1205 Begin at all sites except MK, which begins later. 1205 %BR weather station has broken fiber optics 09267 cable. May affect data from index of refraction model. 1205-1557 *PT unusable due to broken ACU. 09286 100 232 1205 KP's & BR's 1cm are slightly warm, should not affect data. 1214 All readbacks okay. 1217-1220 *SC autostowed. Unknown reason.
