Just completed the design of a cloud sensor to replace the one that died. The system has a telnet server built into the Pi. This allows remote systems to access the sensors and display the IR sky temperature, barometric pressure and humidity. The IR sensor is quite accurate and has internal calibration. As you […] Hi everyone. I need time series data on this system. To include mid minima timing in BJD format. I am starting a research project on this star. Email me if you have any early pre 2009 data. Thanks, John […] Link to the online version.. https://aladin.u-strasbg.fr/AladinLite/ We now have all the elements to fully automate time series star measurement and processing. This includes: JD to BJD conversion Accurate Minima Detection (Using Kwee van Woerden solution) Production of all plots and data files for Phase folded plots. Scripts can be run for specific tasks, like startup, production of calibration frames. The […] The paper is now on the archive of scientific papers: https://arxiv.org/abs/1911.00125 Quite a significant amount of new data from our group. Some interesting departures from early expectations. It will clearly take some ongoing research to identify the mechanisms that are producing some of the effects. Seems to be getting some interest! […] Yes, I did it once while I was building a new observatory. It took me just 3 hours to build!! Roll off shed design. Thick marine ply base with 6 castors to help keep it from flexing, cut out for scope pier. Even put in a dehumidifier. Mine was a bit messy as it […] New light curve for NSVS14256825 binary. Standard plot of mag against time. Check plot to look at a check starGetting a bit low (30deg at end) […] Great night for planet spotting. Really nice stable conditions. Also got a quick pic of M51 single frame 500sec. M51 no filter 500sec. Also got a really nice plot of NSVS 01286630 Orbit 11499 primary eclipse. Mag against time 170 images at 60 sec […] Not the usual view of the moon.. Taken with my phone! Partial eclipse How to Get Started With Astronomy While on a Shoestring Budget Thanks for writing this handy guide.. Now in the LINKS page. |
