View from the Tanegashima webcam a few minutes ago - horribly overexposed, but you can just make out H-IIA F39 on Pad 1, in the far right of the image.

And here's William's launch article:
https://www.nasaspaceflight.com/2018/06/japans-h-iia-rocket-igs-radar-6-launch/

Quote
Japan has not announced whether the Radar 6 satellite on Tuesday’s launch is a fifth second-generation spacecraft, or the first third-generation radar mission.

Q1. Are there any document-sleuthing or amateur satellite observing methods that could answer this question?

Q2. Will this launch use the 4S payload fairing?

Slightly better view from the webcam - hard to say for sure given the quality, but looks like a 4S.

For Q2, it was indeed the 4S fairing being used - check out the photos from people on site on my Twitter account.

IGS Radar 6 has separated from the second stage, both are in sun-synch low Earth orbit. Mission success for the Japanese rocket.

Max-Q condensation shocks hi-res pictures in this tweet.

Chris #1 tweeted this out, so it's worth clarifying that these condensation clouds are NOT necessarily indicating Max Q.  A vapor cone typically occurs as the vehicle approaches transonic speeds, which MAY happen to coincide with maximum dynamic pressure, but not necessarily.  In fact, in orbital rocket launches, Max Q normally occurs in the low supersonic regime, right? (It depends on the acceleration profile, which depends on the thrust to weight ratio.)  So Max Q is more like a dozen seconds or so after the transonic regime in which a vapor cone is seen.

These kinds of condensation clouds can be observed on humid days on regular airliner wings or engine nacelles as they approach or depart an airport.  And those are hardly transonic or even Max Q scenarios.

This kind of image is also sometimes mislabeled as "breaking the sound barrier".  Nope, not that either, but typically close in time, as per above.

PSA #1: EST does NOT mean "Eastern Time".  Use "Eastern" or "ET" instead, all year round, and avoid this common error.  Google "EST vs EDT".
PSA #2: It's and its: know the difference and quietly impress grammar pedants.  Google "angry flower its" .  *** See profile for two more NSF forum tips. ***

All very true, thank you for the clarification. in fact, the condensation clouds in the Prandtl-Glauert singularities in these cases follow the shockwave airflow, and they roughly coincide with parts of the vehicle accelerating the flow to past supersonic speeds, while the vehicle itself may be subsonic. Thus the sound "barrier" nickname (since they usually occur in rockets when the "singularity" is approached at Mach 1), or the Max-Q language since it roughly coincides with when pressures are becoming the highest. Even though, as you say, the clouds may coincide with neither single event.

My thanks as well--I couldn't stay up to watch the launch live; so I'm thankful for this thread!

Object C now cataloged. Most of the IGS Radar series have had such a debris object associated with them,
possibly related to radar deployment hardware?
