- | //Last update: 4. April 2017 - AK// | + | //Last update: see bottom right// |
- | Today, a major repair of the telescope track started. That will last till May 12. Until April 18, | ||
- | limited observations will be possible (Azimuth range ~ 220-280 deg), after that no telescope | ||
- | movement at all will be possible. | ||
- | All secondary focus receivers are up and running; the 7mm system has only one polarization working (RCP). | + | **Receivers currently installed at the prime focus:**\\ |
+ | ^Receiver^Status^ | ||
+ | |P210-7|ok| | ||
+ | |P200/180|ok| | ||
+ | |P170 / UBB|currently under maintenance| | ||
- | Prime focus receivers currently available: P210-7, P200, P10, P22, P3. | + | Please note, that there is new strong RFI at ~1475 MHz, influencing |
+ | also the protected band. The staff of the observatory is currently | ||
+ | investigating possible measures. | ||
- | Please note, that the S45 receiver (aka C+-band) is still under commissioning. If you want to use it, please let us know beforehand. | ||
+ | **Receivers currently available in the secondary focus:**\\ | ||
+ | ^Receiver^Status^ | ||
+ | |S130|not available | | ||
+ | |S110|ok, wider bandwidth with the new EDD system - please contact staff| | ||
+ | |S60|ok, only one horn available | | ||
+ | |S45|ok | | ||
+ | |S36|not available | | ||
+ | |S28|ok | | ||
+ | |S20|ok | | ||
+ | |S14|ok | | ||
+ | |S7|ok | | ||
- | \\ | + | The S-band has recently heavily been occupied by RFI (due to LTE). Observations with the 11cm-receiver should use the 8-bank polarimeter or the new spectro-polarimeter (please contact staff).\\ |
- | __Outlook:__ | + | |
- | + | ||
- | + | ||
- | During Jul 5 - Sep 1, our usual summer works will be done (telescope painting / corrosion protection). | + | |
- | In this time, the time between 0800-1900 hours on Mo-Fr will be unavailable for observations. | + | |
