The Hinode Solar Optical Telescope Focal Plane Package contains three CCD cameras: Filtergraph (FG), Spectro-polarimeter (SP), and Correlation Tracker (CT). The FG camera suddenly developed an electrical short circuit on 2016 February 25, after 9.4 years of operation on-orbit, and it was promptly switched off. The other two cameras are unaffected, and science observing resumed with the SP and CT on March 3rd. The FG camera collects both broadband and narrowband images, so neither type has been available since Feb 25th. After a thorough investigation of the anomaly, it was determined that the FG camera will remain off in order to not risk significant damage to the SP or CT.
Hinode and SOT continue a full schedule of observing, including Hinode Observing Programs (HOPs), and frequent coordination with IRIS and other observatories. The telemetry previously used by the FG has been allocated amongst SP and the other two Hinode instruments, resulting in large increases for EIS and XRT, especially when observing targets at the limb.
The added telemetry enables new observing modes for each of the instruments:
- Collection of more fast time series
- Full-resolution maps of the photospheric vector magnetic field and other atmospheric properties
- Higher cadence observations (down to 2 seconds for small FOVs and short time periods), particularly for wave studies
- More filter combinations
- Larger FOVs (additional synoptic programs)
- Increased line coverage
- Higher cadence
- Increased use of mosaic programs
These features will also be integrated into Focused Mode observational programs (see SolarNews notice from September 1, 2016 for more information). The Focused Mode planning calendar is available at hinode.msfc.nasa.gov/status.html
Additional programs for taking advantage of increased telemetry are being considered and suggestions from observers are requested through the IHOP program (hinode.msfc.nasa.gov/hops.html).
Requests for further information can be sent to the Science Steering Committee. Points of Contact are listed at hinode.msfc.nasa.gov/hops.html#pocs
Following a change to the SOT operating mode, a revised telemetry allocation was agreed by the SWG for Hinode normal mode operation:
SOT XRT EISPreviously the EIS telemetry allocation was 15%.
Disk Mode 54% 23% 23%
Limb Mode 14% 43% 43%
For SP polar observations, the disk mode allocation will be used. However it is possible for an observer to request the higher limb mode allocation for disk observations that would benefit from additional telemetry.
Examples of ways to use the additional EIS telemetry allocation are:
For the Hinode mission as a whole, the possibility of operating in “focussed mode”, during which commands are uploaded to the spacecraft at weekly rather that two or three day intervals, allows long term studies of evolution in selected targets e.g. coronal hole boundaries, quiet sun network. It is important to make use of this mode as we approach solar minimum.

The open-access journal Living Reviews in Solar Physics has published a new review article: “Inversion of the radiative transfer equation for polarized light” by Jose Carlos del Toro Iniesta and Basilio Ruiz Cobo on 23 November 2016:
del Toro Iniesta, J.C. & Ruiz Cobo, B.,
“Inversion of the radiative transfer equation for polarized light”,
Living Rev. Sol. Phys. (2016) 13: 4.
This article reviews our current understanding of modelling convection dynamics in stars. Several semi-analytical time-dependent convection models have been proposed for pulsating one-dimensional stellar structures with different formulations for how the convective turbulent velocity field couples with the global stellar oscillations. In this review we put emphasis on two, widely used, time-dependent convection formulations for estimating pulsation properties in one-dimensional stellar models. Applications to pulsating stars are presented with results for oscillation properties, such as the effects of convection dynamics on the oscillation frequencies, or the stability of pulsation modes, in classical pulsators and in stars supporting solar-type oscillations.

The first Applied Space Environments Conference (ASEC), co-sponsored by Universities Space Research Association (USRA) and NASA, will be held in Huntsville, Alabama on May 15-19, 2017.
The Applied Space Environments Conference is a forum for the space environment engineering and applied space science community to discuss the discipline's ability to support current space programs and to identify gaps in knowledge and technology needs required for future exploration goals. Space environment hazards need to be considered during all phases of human and robotic space exploration, from the initial design of a space system architecture, through testing and construction of space systems hardware, and finally during mission operations in order to assure safe and reliable operations to meet program goals. Applicable environments will include those that impact human health, spacecraft design, and mission operations in low Earth orbit, through the Earth's magnetosphere, and into interplanetary space as well as environments of other planets, moons, and asteroids.
Abstract submission, registration, and venue information will be posted in the next announcement. Please refer to the meeting website for a full description of the conference and a general list of topics to be addressed. sti.usra.edu/asec2017
