Good day all,

It was suggested that I pass the following note along to the Max Millennium Science Group. I will also add that the next call for proposals will likely be sometime in April of 2017.

Thanks,

Adam Kobelski

Coordination with ALMA observations of the Sun is high priority for both the IRIS and Hinode missions. IRIS and Hinode provide observations from the photosphere to the corona that are ideal complements to the chromospheric measurements with ALMA. During the upcoming ALMA cycle 4 solar observations from December 2016 to April 2017, IRIS and Hinode will prioritize support of successful ALMA cycle 4 solar observing proposals.

We suggest that PIs of accepted ALMA proposals inform the Hinode and IRIS teams as soon as possible of the desired observational support — our teams will be happy to collaborate with you to tailor the coordinated observations to your science goals. We suggest that successful ALMA proposers submit a request for an IHOP (IRIS-Hinode Operations Plan), see http://hinode.msfc.nasa.gov/hops.html#requirements for details.

Please keep in mind that while IRIS is in eclipse season from early November through mid February, during this time frame IRIS will nevertheless be able to provide high quality observations for about 60 minutes out of every orbit (97 minutes). To maximize overlap with IRIS, requesting at least 1.5 hours of ALMA observations is the best option. IRIS has no limitations for ALMA support from mid February onwards.

As the observation date nears, close communication on the timings and pointings of the ALMA observations will be required in order to allow Hinode and IRIS to coordinate successfully.

If you have questions about support for ALMA observations, please contact Sabrina Savage (sabrina.savage@nasa.gov) for Hinode and Bart De Pontieu (bdp@lmsal.com) for IRIS.
