Bon Echo Posted March 29, 2018 Share Posted March 29, 2018 Looking for player(s) interested in creating an ISS Sighting waymarks on Monday May 21st. The station will be close to overhead in Houston Texas (hint hint) and will track just south of the Great Lakes. I'm in Hamilton Ontario and for me the station will pass with a Maximum altitude of 70° and a brightness of -4.0 at 22:13:35 eastern time http://heavens-above.com/gtrack.aspx?satid=25544&mjd=58260.0927771395&lat=43.2599&lng=-79.8494&loc=hamilton&alt=86&tz=EST In Houston, the station will pass with a maximum altitude of 78° and a brightness of -3.7 at 21:08:43 central time http://www.heavens-above.com/gtrack.aspx?satid=25544&mjd=58260.0894001302&lat=29.774&lng=-95.3576&loc=Houston&alt=16&tz=CST Probably more than a few waymarkers in between those two locals, could possibly set up a three-point sighting. Two nights ago I finally made it out to see the ISS, it was max alt 82° and so bright and now I'm hooked! Went out again tonight to watch it pass at max alt of 42°, what a big difference. I may have missed it, but most passes between now and late May that are high enough are from Northwest to southeast (from Hamilton to Pennsylvania), so it's harder to get the minimum distance, or they are early in the morning. I'm not interested in getting up at 5 am to look at some light in the sky. Thanks 1 Quote Link to comment

That would work on this end - except that is the Sunday of a long weekend (Victoria Day weekend in Canada) and we may be further south at the Allegany Geobash.

vulture1957 Posted March 29, 2018 Share Posted March 29, 2018 Contact The Snowdog and Cldisme (in Joliet IL) to see if they'll play. If so, I'll watch the overpass and visit all your waymarks! The Snowdog and I are really in the same area, and I already got my waymark, so I'll let The Snowdog get this. If he can't do it, I'll make myself available. 1 Quote Link to comment

(sp) You are correct. In the Summer, even when we are in the dark of night, the ISS is still reflecting the sun's rays that come from over the Arctic. Bon Echo picked the right pass. It stays in sunlight all night and produces a 9000 mile (14,484 kilometers) path on which to find partners. The path starts somewhere in the Pacific ocean off the coast of Mexico, and stops at sunrise in Mogadishu, Somalia on the East coast of Africa. Quote Link to comment

They are 2 different passes. It's even possible to do 2 passes on the same day with a different partner for each pass. Example - On May 21, early in the morning, the ISS passes over the Philippines, across the Pacific, over Eugene, Oregon, heading SE between Las Vegas, Nevada and Salt Lake City, Utah, then passes over me at 06:10 am. In the evening the ISS passes to my NW at 21:10:16 pm, passes to the SE of Benchmark Blasterz at 21:11:46, over Bon Echo in Canada at 22:16:17, and then continues on to pass over the France/Spain Border. First priority should be given to Bon Echo and The Snowdog. I don't think either of them have created a Waymark for this Category. Both must view the ISS at an Alt greater than 45°. Now the Problems: 1. For the ISS Pass on the evening of May 20, The Snowdog is viewing the pass at an ALT of 89°, which is almost straight overhead. Bon Echo will be at the Geobash in New York. He said in a message here on March 29 that the ISS would pass at Alt 48°. Because the pass is slowly moving to the NW, the Alt is now at 46°, and will drop below 45° by May 20. He will not be able to Waymark that Pass if he stays at the Geobash. 2. For the ISS Pass on the evening of May 21, Bon Echo is viewing the Pass at an Alt of 74° in Hamilton, Ontario, which is good. For The Snowdog, the chart is showing an Alt of only 38°, which is too low. Don't despair. The ISS path moves a little to the NW each day as the path is recalculated, which means the Alt will rise a little each day. By May 21, the Alt may be at or above 45°. Lets wait and see. Meanwhile, we still have Benchmark Blasterz and myself prepared to pair with Bon Echo, if needed. 3. Max and 99 and Benchmark Blasterz are too close to pair with The Snowdog. They are all in the same minute of Flight Path. We need another person at least 300 miles northeast or southwest of Oklahoma City to observe the May 20 Pass with The Snowdog. Quote Link to comment

I didn't realize that the parameters are recalculated each day. I thought the times and altitudes that are posted now are what they will be (or very close anyways) come that date. Lets see how it looks in 3 weeks from now. Quote Link to comment

I explained how to do the search yourself in this forum about a year ago - see below for a refresher course. All viewable ISS Passes for you in Los Angeles that go from SW to NE also pass over Minnesota and States between. I also mentioned in the past that an ISS Pass that flies over Texas to the Great Lakes region will pass over near Los Angeles on its next pass in 90 minutes. Therefore, You probably have visible passes on either May 20 or May 21 or both. Quote Link to comment

+8Nuts MotherGoose Posted April 24, 2018 Share Posted April 24, 2018 (edited) Here's a recap of Events for the ISS Pass on May 21. When Bon Echo, in Hamilton Ontario, first posted on March 28, he said the ISS would pass on the 21st at altitude of 70° (To his SE) at 22:13:35 eastern time. Now, 26 days later and about 1/2 the original time to May 21, the ISS will pass at altitude of 88° (To his SE, almost directly overhead) at 22:25:18 eastern time. Changes from original are; rise in Altitude of 18°, time is later by 11.5 minutes, and the Ground path has shifted to the NW by about 100 miles. At my Location in the South tip of Texas two day after Bon Echo's post, The ISS would pass on May 21 at Altitude 70° to my NW at 21:09:55 Central Time. Now it is at Altitude 46° to my NW at 21:19:19 Central Time. The Altitude has dropped 24° and the Ground Track has shifted 130 miles to the NW. By May 21 the Altitude will be well below 45°. To stay in an area where the pass is greater than 45°, I am planning a trip. I will travel 500 miles to the Odessa, Texas area to observe the ISS Pass on both May 20 to the NW and May 21 to the SE. I will be greater than 1 minute of flight time from Dallas and Oklahoma City. I still have hopes of finding a partner willing to get up at 4:00 am in France, Spain, or Portugal to observe one of those two passes. Edited April 24, 2018 by 8Nuts MotherGoose Edit to clarify.

This is about a month away and the pass will shift about 160 km during that time toward the Northwest. I think it will still be greater than 45° for both of you.

Keep a watch on it once a week. Everything will change as the flight path gets recalculated. You will see that the center time will change and the Max Alt will change which are the two items most important for you. Also, six lines above that pass is the pass that starts with 21 May 3.1... That is the ISS Pass that starts on the evening of May 20, crosses the United States, goes over southeast Canada, across the Atlantic, passes midnight and changes dates, and comes to you from the NW at 04:31:34 at Max Alt of 54°. The entire flight takes place during night time, but the ISS is reflecting sunlight and can be seen during the entire flight. Remember, those times and altitudes will change as we get closer to May 21. You will be working with myself and others to create the longest series of Waymarks along a single flight pass.

At the bottom of my post on April 17, I show my original postings about the ISS from a year ago. It teaches how to search the Heavens-Above web site for ISS Passes near your home. Yesterday, razalas went to that previous post, learned how to do it, and then posted a photo of passes near his home. The ISS goes as far north as 53° Longitude. From Paris, any ISS Pass that goes north of Paris is viewed from Paris at greater than 45° Altitude. There are at least two Passes greater than 45° Altitude every night from May 14 to May 30. At least one every night looks similar to this photo. Edited April 25, 2018 by 8Nuts MotherGoose corrected spelling. Quote Link to comment
+8Nuts MotherGoose Posted April 25, 2018 Share Posted April 25, 2018 Another requirement is the observers must be at least 1 minute of flight time from each other. 1 minute of flight time is 472 km or 293 miles along the flight path. We determine the time by using the time listed for the Max Alt. If an observer in Paris sees the ISS at Max Alt at 02:19:25, the other observer must see it at Max Alt on or before 02:18:25 OR on or after 02:20:25. We can have an Observer in Paris work with an Observer in Ireland because they are more than 1 minute of flight time apart. However, an Observer in Paris, and an Observer in central United Kingdom, although more than 472 km apart, are still observing the ISS during a period that is less than 1 minute of flight time. See photo for illustration. We know that each observer must see the ISS at the Max Altitude equal to or greater than 45°. This requirement is to give the Observer the ability to see a bright object, rather than "I think I saw it just above the horizon, but I'm not sure." The time of Max Alt is also used to locate where you are along the flight path in relation to other Observers. You are not required to see the ISS at the moment of Max Altitude. On a partly cloudy night, you observe the ISS moving across the sky toward you and it goes behind a large cloud before it reaches Max Alt and is never seen again. You saw it. You can claim it. You still list your Max Alt and time just as if you saw it during the entire pass. Add a note in your Waymark that it was partly cloudy and you only saw it before it reached Max Alt.

Bon Echo Posted May 10, 2018 Author Share Posted May 10, 2018 We're less than 2 weeks out from these pass-overs. They are still good for me for multiple days and times between May 20th and 24th. There are several players interested in there passes, I'm not sure anymore who's all in for each of the potential passes. I will be in Hamilton Ontario Canada on all days over that time period (no Geobash for me this year). here's a list of dates, times (for max altitude - Eastern Time zone), and max altitudes for me: date brightness time max altitude 20 May -3.9 05:03:42 62° [although I really don't want to wake up at 5am] 20 May -3.0 23:20:06 51° 21 May -3.9 22:27:35 89° [this is the one I'm most interested in] 22 May -3.7 21:35:08 49° 24 May -3.6 21:26:30 74° If others prepare a similar table for their location, I think this will make it easier for us to choose partners.
