Objects Observed 24014
Log Obtained ~9 hours of 24014. It is a bit of a strange bird. The last couple of nights have shown similar, but smaller amplitude variations than I saw earlier. Sometimes, I think Canopus is to blame. For now, though, there is no other reasonable target out there. I tried something a bit different this time around with regards to telescope pointing. I used my pinpoint script to do plate-solved adjustments of the telescope tracking between observations. It did not add considerably to the overall delay between measurements and may help to address some strange star matching issues with Canopus (i.e. when the FOV is moving around a bit, which it does with SEO). This system worked like a champ for the first few hours – consecutive FOVs were dead-on. However, drift occurred later in the night. Don’t see how this could happen unless the pinpoint script was failing for some reason. Added some debugging and a fallback action just in case. Let’s see what happens on 12/20.

I will set my max cloud threshhold higher (e.g. 0.75) and use the actual images to decide. Also, I was unable to get flats, so I have not analyzed the data yet. The image format has changed due to the scan strip, now in pixels 1-14. Will get some flats tonight, hopefully.

It was a little complicated at the beginning with Matt having to hand the telescope over to me and the dome did some weird things (closed a few times randomly and gave me the error tx keep dome open command failed and Matt did not close it). Over all it was a very successful observing run.

Slack warned me (and probably everyone else who has notifications turned on for that channel – maybe we should tell people how to mute it?). I didn’t have the ccd reset instructions handy (or password), so shut it down. I will be ready next time. The autopointing script worked well. Made some additional tweaks and will give it another try next time. Overall, Viv’s efforts brought the pointing within approx. 1/10 degree for both ra and dec. The autopointing script provides another order of magnitude. Will try it through the GUI command window too at some point. Need a new name for it…

Objects Observed 2798 Vergilius
Log Mostly successfully complete a twilight flats sequence using the “skyflats tarid=3” command. Started the routine around sun alt=0.0 (230UT). It auto calculates the required exposure for different filters, starting with halpha (at least, it says halpha) and moving towards clear. However, I “ran out” of bright time (got too dark to do flats), and the routine quit. Next time, I will start a bit earlier? sun alt < 10 deg.?

I configured an observing script to look at 2798 Vergilius for ~5 hrs (90 s exposures, with darks mixed in between). However, I forgot to change the filter back from g-band (last left by skyflats routine) to clear – ooops! Also, the CCD stopped responding (ERROR Findkey null msg=ccd_status in=nrow=) approximately two hours into the observing sequence. Images were obtained after this time. However, although the FITS header indicated 90s exposures, the images were progressively darker. In addition, the whole sequence which should have taken ~5 hours, only took ~2 hours.

Pointing is still a problem. I had to use “tx offset dec=0.25 ra = 0.0167 cos”. I was able to calculate the offset by doing a few pointing tests, downloading the FITS files, and uploading them to astrometry.net. Worked very well.

Having a great time. Learning a lot! Look forward to trying again post-full Moon!

Objects Observed m5, ngc4125
Log Everything was working great- had to move the telescope after slewing because I wanted purposefully off center images.
Imaged off center m5 and supernova in ngc4125- can no longer see the supernova well so it appears to be fading.

Log Actually not sure what time it was but I did login to check everything on Th night the 14th local time in Sonoma. The filter was on u-band. I closed down (even though I had not opened up) in order to reset the filter wheel. Not sure what is causing this filter wheel issue but it is good if we keep track. Time above is guessed. I will check time more carefully next event. One can type ut in command lines to find out the universal time.
