Babuyan Island is now being hammered. It won't be long now before the island enters the eye!

Eye now passing over Calayan Island. The weather station (★ WMO 98133) on the south side of the island stopped transmitting obs after 21Z, unfortunately, so we'll have to wait for PAGASA to release the data.

The station at that time was ~25 nmi from the eye of Ragasa. Using RMW of 22-23 nmi (calculated by @JoshuaCAgar), Schloemer equation outputs central pressure estimates between 915-920 mb.

It does seem like intensity has recovered a little since this morning, despite the JTWC best track indicating that pressure has filled in to 930 hPa as of the latest fix.

The latest subjective fixes (at 18z) were T6.0 but ADT numbers over the past 2 hours have climbed back over 6.5. If the trend holds, I wonder if Ragasa might not regain super typhoon status this evening.

Microwave has an outer eyewall still. Hard to re-intensify with that structure.

As has been said before, an outer eyewall has been present on microwave imagery:
