Hi All, Question first so I don't forget. Is there still a little airfield out by Cedar Fort where you could observe from the parking area? Are airport lights on all night? I'm trying to find a place that's moderately dark near Eagle Mountain--for the convenience of a new friend. Open to other suggestions, of course. Had an excellent view of the reappearance from Orem Lakeside Sports Park. Amazing to see Mars peak out and suddenly be easy to see naked eye. One of the coolest thing I remember seeing was Mars occulting many of the Pleiades. I have not been able to find any info on when that should happen again. Just a great memory.

Thank you, I was going to find this info later tonight. I guess that changes my planned viewing of this.

Hi,
I just put together some info from a long list of timings (from occultations.org) of the disappearance & reappearance of Mars and if anyone's interested in having a look, I've shared it here on Google Sheets:
https://docs.google.com/spreadsheets/d/15_kCgqU2o7B4uVL5LzbC8KEfr4o5VtyuuG_U...
The most significant issue is the altitude of the disappearance. To
see
it from anywhere on the Wasatch Front, you'll need as low a visual horizon as you can get toward azimuth 126 degrees (East is 90, so it's sort of East-South-East) because the altitude is only 4 degrees.
Note that based on other entries, the farther south you are from SLC (not sure the exact coordinates used for it by the program that produced the data), the higher in the sky the event will be (and there is no correction factor for that, but Phoenix shows 11 degrees as opposed to SLC's 4). So, heading farther south will get things a bit higher, but the opposite is also true: farther north means lower.
Hope this is of use! And hoping to find a low horizon on Tuesday morning--and fewer clouds than predicted!
John

I didn't read carefully enough. The latitude/longitude used for calculating the alt/az & timings for SLC is apparently near the center of the airport property. As best I can get Google maps to show me, that's about 2/3 of the way down the B concourse, on the east side. Good luck getting scope and mount thru security ;-)
? 40 degrees 47.3' N 111 degrees 58.7' W??
I'd be interested to hear what you manage to see.

I will actually be within just a couple of miles of the airport but up against the mountains, so will probably have to catch it online later.
