For other boxes, it will come with the next release of Scientific Software Distribution (end of May). May 27, 2000 11:49:17 AM jibsen Percy Glaves got in contact with Richard Hook and the latest version of scisoft has been delayed until middle June. Since we cannot even start without the official scisoft distribution I suggest to delay the deadline in 1 month (July 15). June 01, 2000 4:21:24 PM gandreon New deadline due to late arrival of package. June 21, 2000 9:02:46 AM jibsen Richard Hook just informed that scisoft will be delivered to La Silla June 23 from Garching therefore I suggest to change the deadline to July 15.

Action : A solution should be devised and implemented. Action Log : May 25, 2000 4:05:33 PM gandreon The firm who delivered the antenna has been contacted. May 30, 2000 10:14:15 AM dgojak Evaluating different alternatives, its complexity vs. reliability, ELC proposes a remote control for the heating system that could be activated via modem by an operator. June 01, 2000 4:23:04 PM gandreon A system which does not rely on human intervention is required. Possible combination of sensors (temperature + humidity) should be also investigated. June 03, 2000 6:23:23 PM mmornhin Detecting snow based on temperature-humidity from the meteo station is out of the question. There is very little relationship between these parameters and actual snowfall. Ideas proposed so far include : - a shovel-like device that weighs accumulated snow (unsuitable in my opinion because we need to detect snow as soon as it begins to fall, not when it has accumulated in large amount); - a load cell at the antenna post, to sense weight increase of the antenna (would require machining mechanical parts, developing electronics, and the load cell would need a very high resolution. Additionally there is the problem of filtering out wind loading); - some kind of infrared detector on the antenna (it would be problematic to filter out daylight, it may cause IR light pollution, and the system may need fine tuning during several snowfall events. Such a sensor may also confuse snow with bird droppings); - capacitive sensor strips across the antenna (would require considerable development work); - placing a hood around the existing snow detector, to aid in snow collection (may improve things, but I would not guarantee it); - Using just the ambient temperature to control the heaters (would work well in most cases, but would waste energy during cold weather without any snow, and would not melt off accumulated snow once the ambien temperature goes up). So far I don't see a safe and elegant solution for automatic operation of the heaters, and neither does the antenna manufacturer see one. Any bright idea would be warmly welcome. The requirement are: 1) Switch on as soon as actual snowfall or icing starts 2) Switch off when the snow has been completely molten off the antenna 3) Do not switch on when there is no snow. Just a curious note: Two days ago, when we had low temperature and intense dewing, the snow detector saw H2O, the temperature sensor saw low temperature, and the heaters switched on. They were running at full duty cycle when I passed by the antenna on my way to breakfast on that cold and wet but sunny and snowless morning... June 08, 2000 4:16:29 PM gandreon Since detector proved to work fine when weather is not windy, a hood should be placed arount it (as in fifth suggestion) to ensure snow collection. June 29, 2000 4:29:52 PM gihle Unfortunately no good solutions are proposed. Any good idea is welcome...... July 06, 2000 4:09:08 PM gandreon Done but ineffective. Conclusion: manual control is required. New action(s) will be open when feasible features will be decided.
