NASA is conducting laser communications research from the Table Mountain Facility; please refer to NOTAM # 2/4076 (KZLA-A0316/22). This is a permanent NOTAM flyers in the Baldy/Mt San Antonio area should be aware of. Laser is non-visible. Hazard Zone is 5 NM centered on Table Mountain, based on 18,000 ft MSL ceiling. Min elevation angle of beam is 20 degrees, laser NOHD is >50km.

i just got word from marcum that the laser will be active “no sooner than the 28th”.
it’s looking like a great day to get up and go. be safe out there kids.March 25, 2022 at 10:44 AM #14682
Updated: the FAA has moved the notice into the SW US Chart Supplement:
Interesting, I was not aware of the Mt. Wilson notice.March 25, 2022 at 2:56 PM #14688
A couple more notes:
If it looks like weather conditions are good for flights that may take you over Wrightwood, you can always check with me (6263756556) on the day of to see if we’re operating. An alternate phone # is 6267201988 (Daniel) in case I’m out of town.
While laser protective eyewear is really only designed as a backup protective measure, and although it’s designed to take a direct hit, there’s always the chance of a stray reflection coming in the side. But if you’re interested, the correct specification would be Optical Density (OD) of 6+ for 1064 nm.

Been there many times. Found a couple tracks. Also built a beefy rebar cage for a telescope base.Hopefully, we can call and see if the airspace is hot or not.March 25, 2022 at 6:48 PM #14691
Another pilot saw this and posted to the SD group. Looks like the NOTAM was cancelled? I have not yet confirmed.March 25, 2022 at 7:15 PM #14692Jerome DaoustGeneral Member
Marcum mentioned in a posting above… “the FAA has moved the notice into the SW US Chart Supplement”.
Which can explain the cancellation of the NOTAM, but the concern remains.March 25, 2022 at 9:07 PM #14693
Ah – I missed that detail. That makes sense.March 26, 2022 at 7:01 AM #14696
As Dan DeWeese mentions, the best thing to do is call (see phone numbers in this thread). The precise schedule (including azimuth and elevation angle) will be known 24 hours in advance.
The mission test phase starts the week of 3/28/22 and runs for one year after launch (August or September, 2022), unless it gets extended (which often happens). Read about the mission here: https://www.nasa.gov/directorates/heo/scan/opticalcommunications/psyche-dsoc/.
From a long-term perspective, this facility (https://scienceandtechnology.jpl.nasa.gov/optical-communications-laboratory) will be continuing to operate for the foreseeable future. However, except for DSOC projects, the lasers are lower power, and do not pose an eye injury hazard.August 29, 2023 at 11:01 AM #18812
FYI – the Psyche Mission launches October 5, so expect a fair amount of laser activity in the days and weeks following.
Flyers are urged to avoid the 5 NM area to the south of Table Mountain. Check with me for schedule (6263756556) or Daniel (6267201988) if your flight plan takes you in this area.
