    I wanted to give you a heads up that DSOC 2.5 hour laser operations will be transitioning to daytime in July. Two of the passes will start around noon and the other three passes will start closer to 5 pm. The two passes close to noon will transmit the lasers for half of the pass (~1.25 hours) at most. The laser safety system continues to work with no issues and we foresee no issue with its operation during the day based on past testing.

    There is an update to my phone number: 626-710-8645

    Update on laser schedule from the project:

    “Our passes through June 3 will continue to start after sunset (but will be shortened to just 2.5 hours starting April 1). The 3 passes from June 10-24 may start up to one hour before sunset. In July, we are planning on doing uplink-only passes (up to 5 of these) during the daytime, but the hours are still being finalized.”

    If you plan to fly in the area during these times, please contact either:

    Marcum Martz 626-710-8645, or Daniel Atamanczyk 626-720-1988.

    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.

    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.

    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.

    Updated: the FAA has moved the notice into the SW US Chart Supplement:

    Interesting, I was not aware of the Mt. Wilson notice.
