Lightning storm

The lightning storm that affected the weather station also caused various problems in the telescope building. The lower hatch of the dome had some fuses blown, while the upper hatch had a function fault which might have been caused by the dome part just above the sensors on top being pressed down some mm as the dome was hit in that area by lightning. The GPS time server for the TCS was also damaged. Its antenna is sitting just inside of the dome at the top of the telescope and the suspicion is that it conducted some (part of the) lightning which damaged the GPS unit internally. The TCS is now using the general computer time server in the service building, while we still have the old stand-alone clock system as a back as well. Depending on the cost of repair, we might consider not replacing the GPS unit.
