Hello, I remark the following ... OccultWatcher shows me some events in the shadow path, but OWCloud shows most of the time a different path (no more in the shadow). When does OccultWatcher actualise the data ? I expect that it uses the same information ... or at least after a manual update. But it is not the case. Here an example ... in OccultWatcher: "I'm in" ... in OWCloud: "I'm out". In the file "prediction_1", that is an old prediction (it seems that what OccultWatcher uses) and in "prediction_2", that is the last prediction. Regards, Jean-Francois

Hello Hristo, I have a proposal for a simple graphic showing all the event quickly with the local horizon directly in OccultWatcher. I have the problem that now near all the events are blocked by the next house. Here the events for my home station for June. I tried to export all the event in Excel format ... but the important information is missing ... no star azimuth or elevation are exported from OccultWatcher to Excel. Alternative ... I could update my Add-in with a new function .... so is it a way in OccultWatcher for an Add-in to select all the events ? Regards, Jean-Fran?ois

Hi Hristo, I notice my exact locations displayed in OW are offset in OWC, When i add a new location in OWC and specify exact, then the station continues to be offset on OWC. (but correct in OW). Is there a away of getting OWC to display the exact station locations ? This would be helpful for mobile observers setting up a fence (say). A mobile phone would show the actual locations. An idea: I note that the locations are offset when not logged in. Perhaps the exact locations could be displayed using a login as a switch that authenticates the observer. That would preserve the location anonymity when a login is not supplied. (if that makes sense). Thanks Tim

I am working with event (7852) Itsukushima occults UCAC4 339-105616 occurring on 12 May, 06:25:59. I had selected a mobile location from which to observe it, but it turns out that I had to change locations. This isn't anything new for me. To facilitate the change, I cancelled all stations for the event and then selected a new location using "Add to my events". This new location is closer to the center line than the original location. After adding the event, OW refreshes and displays The station locations on the pink/blue overhead view. When I use the "Save 'Google earth' kml file" feature, the following is displayed in Google Earth. In OW, the big black bar is my Home location which looks correct on the pink/blue chart, near the southern, but the new location of the mobile site is nowhere close to where it is suppose to be. the kml rendering shows the location to be just south of center line, but the pink/blue chart in OW shows it well to the north of the center line. I triple checked the Long/Lat/Elev in both the placemark in Google Earth and the site coordinates in OW and they match (OW stores the long/lat only to 5 decimal places whereas Google Earth store them to 6). I restarted OW and the behavior is the same. I then clicked on "Show online map with stations" and this is what is displayed. My site is in the correct location, but the pink/blue, as it is in OW doesn't place my site in the correct place. Is this part of the new feature of OWC? the "white line seems to be match the location where the pink/blue (i don't know what this is called) shows it. So many questions. Do I have to consider the White line when attempting to decide on where to observe? The save kml feature of OW doesn't show the white line. will OW have that feature soon? I have updated all my OW sites to include the elevation from Google Earth. The elevation corrections are a good thing, but everything needs to be synced in order to make event planning more accurate.

OWC update has been now released. A few notes on how the plot works right now in Phase 1. The shadow path (green, blue and red lines) are non-elevation corrected. The telescopes are the actual locations of the submitted stations. The chords (while or orange lines) for newly submitted stations are the elevation corrected chord relative to the path of the shadow. After selecting a location on the GoogleMaps OWC will obtain the elevation for the location and then will draw two white lines as per the image below. The white coord will be where the actual position is going to be related to the path, in the image below while the selected location is close to the non-elevation corrected center line (green line) the elevation corrected path puts the location outside of the shadow (between blue and red lines): The position of the chord on the OW Plot will correspond to the elevation corrected chord. See how on the plot below the chord is in the 1-sigma zone: The altitude can be also manually entered or updated which will cause the chord to be updated, too. I hope that all this makes sense. In phase 2 the entire path will be elevation corrected and the chords will run through the selected location, while the shadow path will be moved accordinly. So once Phase 2 is released, for the above example the while chord line will run through the telescope and the green line (and rest of the path) will be shifted to the lower right, leaving the white cord path again between the elevation corrected blue and red shadow lines. Please note that all current chords submitted before this version will not be elevation corrected so the elevation correction for planning should be considered functional only for future stations.

In OW Desktop you can now enter a MSL altitude for all of your saved home sites and this will be used when computing event circumstanes locally on your OW Desktop. OWC will be updated this weekend to query the SRTM elevation database for the elevation of any sites you are adding in GoogleMaps. The UI / user eperience should be self explanatory but let me know what you think. I have done accuracy testing to ensure elevation corrections are computed correctly. As this is a massive change I expect that there will be feedback and potentially issues that I will need to fix in the next weeks to come. So please provide feedback and report any issues you may have spotted. Hristo.

I am gonna try to capture the "Zelinda" occultation tonight (2023-04-27 00:39:54). My location on the attached screenshot is the yellow circle to the left of the "N" in New York. Can someone point me to documentation that explains these lines. Even a quick description of my chances for this event would be very helpful. I will be trying the Dynamene event the following day also. thanks Steve H
