Has anyone info on the eight CubeSats to be on this launch?

Only that it's manifested by Spaceflight Industries for a US remote sensing constellation.
Maybe another PlanetLabs batch?

I think I have seen sources that report that they will not fly on this flight, although the launch plan (attached in this post) still list them.

It looks like weather forecasts will be tricky for the launch time, but so far the status is go.

I visited Sagamihara a few years ago to meet with the ASTRO-H team and share with their data analysis team lessons learned from the Chandra program.

ASTRO-H is an exciting mission. Its cornerstone instrument is the SXS, a microcalorimeter at the focus of the SXT soft X-ray telescope.
We hope this will be the first working microcalorimeter in orbit. Compared to the CCDs on Chandra and XMM and Suzaku, the pixels
of the SXS have far higher energy resolution - like going from 8-bit color to 32-bit color, I guess. Their resolution is better in some
energy ranges than the gratings on Chandra, which have the disdavantage that their light gets spread out over the detector, so
you only get a measurement of one source (star) instead of a whole picture - with a microcalorimeter you get a measurement (high resolution spectrum) in every pixel of the image.

Now to be fair, the SXS has only 36 pixels and the SXT is a fairly poor imaging telescope so you'll only really get one source at a time
with ASTRO-H too. But this is a critical test of technology that will supplant CCDs for X-ray imagers, for example on the proposed X-ray Surveyor mission now being planned (plotted?) by the US community.

It's been a long road. The technology - from NASA/Goddard and JAXA among others - was originally going to be on AXAF.
AXAF was in about 1991 split into AXAF-I and AXAF-S to save money, with AXAF-I  for imaging and AXAF-S for a calorimeter spectroscopy mission. THen about a year later AXAF-S was cancelled. AXAF-I survived to become Chandra (launched 1999).
In the wake of S's cancellation the US team paired with the Japanese to get their instrument on ASTRO-E, which launched in 2000.
But, it fell in the ocean and was destroyed. So they tried again five years later with ASTRO-E-II (Suzaku). ASTRO-E-II got into orbit
ok and the calorimeter got nice measurements of the on-board calibration source but then due to a design error the thermal
system failed and warmed up all the cryogen, making the calorimeter useless. Suzaku's done great science with its remaining
instruments, but still no opportunity to do astronomy with the calorimeter.  (There have been six calorimeter sounding rocket flights
between 1995 and 2013 in NASA's XQC program, so there's been a little test data).

11 years after the Suzaku fiasco and a quarter century after serious efforts to fly the instrument began, we're hoping ASTRO-H's SXS
will finally do serious astronomy with this technology. Fingers FIRMLY crossed.

https://heasarc.gsfc.nasa.gov/docs/astroh/whatnew/

Feb 8, 2016 - The SXS dewar has been sucessfully topped-off with liquid helium.


https://heasarc.gsfc.nasa.gov/docs/astroh/
SXS is now at 50 mK
7 Feb 2016

- yes you read that right, the temperature of the instrument is 50 MILLIKELVIN.
That is 0.050 degrees above absolute zero.
or, in layperson's terms, BLOODY COLD.
The calorimeter works like this: an X-ray photon comes from space, bounces of the mirrors and
lands in a calorimeter pixel. The energy of the photon - A SINGLE PHOTON - raises the temperature
of the pixel and you measure that, deducing the photon's energy.

As someone said about being an astronaut on top of a rocket, if you're not freaked out by this, then you don't
understand what's going on.

H-IIA rocket No. 30 launch before Y-1 briefing

Is a briefing of reporters who take place in about one day before the launch.
Other launch content of the current H-IIA, development status, is transmitted information such as weather judgment.

US CubeSats were demanifested on this flight due to scheduling issue (JAXA announced Jan. 20th)
Souce is on this Japanese article.

Launch Postponement of H-IIA Launch Vehicle No. 30 with X-ray Astronomy Satellite (ASTRO-H) Onboard

Mitsubishi Heavy Industries, Ltd. and the Japan Aerospace Exploration Agency (JAXA) decided to postpone the launch of the H-IIA Launch Vehicle No. 30 with the X-ray Astronomy Satellite (ASTRO-H) onboard from the Tanegashima Space Center, which was originally scheduled for February 12 (Fri.), 2016 (Japan Standard Time), as clouds including a freezing layer (please refer to the following figure) that exceed the restrictions for suitable weather are forecast to be generated at around the scheduled launch time. In addition, strong winds are also forecast and they are expected to hinder launch preparations.

The new launch day will be announced as soon as it is determined.

Does the current forecast rule out a launch during the February 13 launch window?
How about the 14th?  The 15th?

Still no word from JAXA on a new launch date. If it was launching today, that would be in about two hours time. The countdown clock at the link below is stopped, so I think its a good bet that ASTRO-H won't be leaving today.

Would have expected rollout by now if they were going for the 14th; no sign of the rocket as of 22:25 UTC so assuming this is now NET 15 February.
