Click [REOPEN] on the dome gui if the clock is not the same as the CHARA time. | The new for 2016 stall detection function usually has each scope disabled each evening. They will need to be enabled before checking the dome servers or slewing. Make sure that the telescopes do not move away from their stow positions when enabling the scopes. If they begin moving, then click [STOW] on the Telescope Control Tab or dome gui and make sure that they arrive at the correct stow position. Check for problems with the dome servers by watching each telescope move to the precise stow position, ie. 89.990º and moving to 90.000º. If it stays off the precise stow position, the dome sever may need restarting. Click [REOPEN] on the dome gui if the clock is not the same as the CHARA time. | ||

On the Main Tab of the Telescope GUI, click [TIP/TILT] under the Pointing Servo menu. If this button is not pressed, then the green dots on the tiptilt windows will drift and eventually drop TT lock. The [STAR ACQUIRED] button on Cosmic Debris also starts the Tiptilt servo for all active scopes with one push of a button. On the Tiptilt Servo Control GUI, turn tiptilt [ON] for each telescope or use the [TT ON] button on Cosmic Debris to perform this function for all active scopes. |

Click [Star Acquired] on the Control Tab on Cosmic Debris to update the target information listed at the top of the Cosmic Debris window. This also turns on all the telescope TT servos, the same function as the TIPTILT button on each telescope gui. Initialize the pointing of the telescopes on your first target by going to the MAIN tab on the obsgtk and clicking the red [INIT] button. Make sure you are on the correct star before initing the scopes or you will have problems. This may have to be repeated if the pointing drifts during the night. This will allow more consistent and accurate pointing for this part of the sky. You can now point to your first science target, calibrator, alignment star or fringe finder and begin the alignment sequence for the beam combiner and then start searching for fringes. |

Click [END NIGHT], then [REPORT] on Cosmic Debris to generate this automatic report email. The report will include the headings: PI name, Program, Observers, Baselines, Weather and Seeing data, and targets on which data was collected. Complete the Observers and Baselines entries, add comments to the bottom of the report and put your name at the end. Check with the observer for completeness of the target list. Some observers will send you comments of their own. Add those to the report. Cut and paste this into an email to CHARA Obs and send it.
